The Payment Card Industry Data Security Standard (PCI DSS) is a crucial regulatory framework that ensures the security and privacy of credit card transactions across various industries. With an increasing number of cyber threats and vulnerabilities, it is essential for businesses that process credit card transactions to stay updated with the latest security practices. One such practice is using a Private Access Point Name (APN) for transmitting sensitive data. While not explicitly required by the PCI DSS, private APNs can provide an additional layer of security for organisations seeking to bolster their network protection.

The Benefits of Private APNs

A private APN is a customised network gateway that allows mobile devices to access a specific private network. By implementing a private APN, organisations can isolate their traffic from public networks, significantly reducing the potential attack surface. This isolation helps to prevent unauthorised access to sensitive cardholder data, thus complementing the security measures outlined in the PCI DSS.

Private APNs offer several benefits, including:

• Enhanced Security: By isolating network traffic, private APNs create an additional barrier against cyber threats and minimise the risk of unauthorised access to sensitive information.
• Customisation: Private APNs can be tailored to an organisation’s specific security requirements, offering greater control over data transmission and network access.
• Improved Performance: As private APNs separate an organisation’s traffic from public networks, they can provide better performance and reliability for data transmission.

Complying with PCI DSS

While private APNs can offer valuable security benefits, it is crucial for organisations to remember that they are not a substitute for PCI DSS compliance. To ensure full compliance, businesses should adhere to the specific requirements of the standard, including:

• Network Security: Implementing robust firewalls, encryption, and secure connections to protect cardholder data.
• Data Protection: Safeguarding stored cardholder data and ensuring that it is only retained as long as necessary.
• Vulnerability Management: Regularly updating and patching software to protect against known vulnerabilities.
• Access Control: Restricting access to cardholder data on a need-to-know basis and implementing strong authentication measures.
• Monitoring and Testing: Regularly testing and monitoring network resources to detect and address potential security threats.
• Information Security Policies: Establishing and maintaining clear, up-to-date security policies and procedures.

While not explicitly mandated by the PCI DSS, private APNs can play a valuable role in enhancing your organisation’s network security. By combining the use of private APNs with strict adherence to the PCI DSS requirements, businesses can better protect sensitive cardholder data and mitigate the risks associated with cyber threats.

Cloud computing has become an indispensable part of modern business operations. With the rise of public cloud hyperscalers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, organisations have been quick to jump on the bandwagon, leveraging these platforms for their various cloud needs. However, the debate over the benefits of public cloud hyperscalers vs. private cloud providers continues to brew. In this post, I’ll explore several reasons why you should think twice about using hyperscalers and consider private cloud companies instead.

1. Customisation and Flexibility

Hyperscalers offer a broad range of services and features, but they often come with a one-size-fits-all approach. This can lead to a lack of customisation and flexibility for businesses with unique needs. On the other hand, private cloud companies can provide tailor-made solutions specifically designed for your organisation’s requirements. This flexibility allows you to optimise your infrastructure, streamline processes, and ultimately reduce costs.

2. Data Security and Privacy

Data security and privacy are critical concerns for any organisation. While public cloud hyperscalers invest heavily in security measures, their sheer size and popularity make them more attractive targets for cybercriminals. In contrast, private cloud companies can offer a more secure environment, with less exposure to potential threats. Additionally, private cloud providers often have more stringent data privacy policies and can comply with specific industry regulations, ensuring your sensitive information remains protected.

3. Personalised Support

Hyperscalers often cater to a massive client base, which can lead to impersonal and sometimes slow customer support. Private cloud companies, however, are better equipped to offer personalised, dedicated support. They can assign account managers or support teams that intimately understand your organisation’s needs, enabling faster issue resolution and more effective communication.

4. Cost Predictability

Public cloud hyperscalers usually employ a pay-as-you-go pricing model, which can lead to unpredictable costs as your usage scales up or down. This variability can make it difficult for organisations to accurately budget and forecast expenses. Private cloud companies, however, typically offer more predictable pricing structures, including fixed monthly or yearly fees. This predictability allows for better financial planning and cost control.

5. Vendor Lock-in Risks

As organisations become more reliant on hyperscaler services, they may find themselves locked into a specific platform. This dependency can lead to increased costs and reduced flexibility, as migrating to another provider may be time-consuming and expensive. Private cloud companies often provide more open and interoperable solutions, allowing you to avoid vendor lock-in and maintain the freedom to switch providers if necessary.

6. Supporting Local Economies

By choosing a private cloud company, especially those operating within your country or region, you contribute to the growth of local businesses and economies. This not only fosters innovation within your area but also helps support job creation and economic development. Moreover, local private cloud providers are more likely to understand the unique needs and regulations of your region, further enhancing your overall cloud experience.

7. Data Sovereignty

Data sovereignty refers to the legal requirement that an organisation’s data be stored and processed within the borders of a specific country or region. Public cloud hyperscalers, with their global infrastructure, may not always be able to guarantee that your data remains within your desired jurisdiction, which can lead to potential compliance issues. Private cloud companies, particularly those operating locally, are more likely to adhere to data sovereignty requirements and ensure that your data remains within the designated borders. This can help you avoid legal complications and maintain compliance
with local regulations.

While hyperscalers have their advantages, private cloud companies offer a compelling alternative for organisations seeking customisation, flexibility, enhanced security, and personalised support. By carefully evaluating your organisation’s needs and priorities, you can make a more informed decision regarding your cloud provider and enjoy the benefits of a tailored solution that aligns with your unique requirements.

Many South African companies had a knee-jerk reaction during COVID and started using whatever connectivity was available to ensure operations could continue while employees worked from home. But what was initially only going to be a 21-day hard lockdown period got extended with varying levels of restrictions, which only ended recently, more than two years later.

This extended lockdown, and subsequent work from home (or from anywhere) model, contributed to a mobile data explosion as SIM cards were purchased in bulk from retailers and distributed to staff.

Between December 2019 and March 2020 (when the lockdown began), Saicom saw a threefold increase in mobile data usage. Since March 2020, until the end of lockdown a few weeks ago, there has been an elevenfold increase in demand for mobile data.

Managing this expanding SIM real estate over the long term has become a challenge for business decision-makers, who are turning to Access Point Name (APN) as a potential solution.

Access point name, or APN for short, is the name of the gateway that connects a mobile network with the internet. Or put another way, the identity of the mobile carrier so that the device knows which carrier network it should connect to. AN APN is like a virtual network overlaid over the Mobile Network Operator (MNO), giving service providers and corporate customers the use of the MNO’s network as an extension of their own.

Despite things returning to a semblance of normality, many organisations are still using APN as a risk mitigation solution and because of its centralised SIM management functionality, businesses have started tapping into numerous other use cases for the technology within their organisations.

Since its introduction in the market, more and more companies have switched from using regular phone lines to Voice over Internet Protocol (or VoIP).  In South Africa, the ageing copper infrastructure and limited capabilities of traditional fixed line telephony make for compelling reasons to look at VoIP as a more scalable, flexible and agile telephony solution, with the added benefit of being able to do more than just make and receive calls.

What is the difference between VoIP and IP telephony?

VoIP is the method used to place and receive phone calls over the internet.  Virtual telephony, virtual calling and online phone systems are other words used to describe VoIP.  

In its day, Skype was the VoIP  platform of choice.  Today, it could be Zoom, Microsoft Teams or Google Meet. When you make a VoIP call, there is no breakout to traditional fixed line networks.  We call this point-to-point calling (Teams to Teams, Zoom to Zoom or Google Meet to Google Meet)

So how is IP Telephony different?  IP telephony uses VoIP technology, but has access to traditional calling platforms. Simply put, you can make calls from your VoIP platform, to a fixed or mobile line or even a different VoIP calling platform.

In this article, we talk interchangeably about VoIP and IP Telephony and refer to both, as VoIP.

How does VoIP work?

VoIP technology is designed to work across a range of devices, including smartphones, laptops, desktop computers and tablets. It uses Digital Signal Processors (DSPs) to encode analogue voice into IP packets and packet switching technology transmits the IP packets over the internet. DSPs then decode the IP packets back into analogue voice on the receiving end.  

This is done as a person to person (or point to point) connection.

Today, many organisations are leveraging their VoIP capabilities and integrating IP telephony tools, to give access to hosted PBX and business communications systems like UnifyOne with Webex or Microsoft Teams.  Not only are they able to make calls to fixed or mobile lines on traditional networks, but they get access to even more useful features like fully featured cloud calling, messaging, file sharing, screen sharing, and more.

5 Ways VoIP can benefit your business

The right VoIP platform allows you to streamline operations and communications, making it possible for team members to work more effectively and with greater ease. 

Choosing the right VoIP platform for your business starts with understanding how it will be used not only today, but also in the future.  It needs to offer scalability to account for future growth in operations. 

Let’s find out more about the benefits of the ideal VoIP platform  for businesses:

1. Reduce costs: cheaper call rates & minimal maintenance costs

VoIP provides businesses with a cost effective alternative to fixed line, on-premise PBX phone systems. It is estimated that call rates on VoIP can be up to 65% less than landline call rates.  

In addition, traditional phone systems require on-site maintenance – which can include call out fees, labour fees and hardware costs, upgrades and additional licences.

With VoIP, business communication is run in the cloud, and managed by dedicated specialists, providing an easily accessible usage dashboard, to monitor incoming and outgoing calls across the telephony environment. 

VoIP upgrades are done in, and via the cloud with nominal impact on the telephony system.

2. Get rid of costly, bulky phone systems taking up critical office space

VoIP allows businesses to streamline their communications by taking operations digital. 

Let’s compare VoIP phone systems and traditional landline systems and their components.

Traditionally an office would have phone lines, connectivity and on-site PBX.  Each component is essential to the system and its effective functioning, and for a growing business this is not only costly, but it takes up space. 

Space that could be used for workstations, meeting rooms or additional office space.  When businesses migrate to VoIP they remove the phone lines and on-site PBX and instead use the data circuits to carry those services.

Some businesses may choose to receive VoIP handsets once connected, but in the modern day, businesses are able to handle communications using their smartphones, laptops, tablets and other devices using mobile and desktop VoIP soft clients. .

3. Better calling features, quality and collaboration

The quality of VoIP calls including the features are often dependent on the reliability of the business’ internet network, a mobile network and the VoIP service provider. 

With a fast and reliable internet connection, and a VoIP service provider with a good  reputation, VoIP calls can create improved speech clarity and provide access to an array of features. .

Maintaining a reliable and secure connection, and being able to communicate seamlessly with crisp audio and video, while collaborating with your participants, can provide more opportunities to pursue quality leads and partnerships, and improve your current workflow with clients. 

A better communication system can stimulate increased productivity and accountability, between team members and clients. Team members can also make and receive calls on the move, by connecting the VoIP service to their mobile devices. This is useful for the modern world of remote work, and team members travelling for work.

4. Uninterrupted services

We know that businesses cannot afford to be offline, or out of reach of customers. 

At Saicom, our uptime for VoIP services is 99.98%, and the white glove service we deliver, means faults and downtime is quickly and effectively resolved.  

To ensure uninterrupted service through loadshedding and power outages, a small and cost effective UPS (uninterrupted power supply) or alternative power supply that keeps the internet router and fibre box running is sufficient.  

You can rely on VoIP being online 

One of the most significant benefits of  switching to VoIP, is the seamless transition to better technology, without losing existing business contact details.

5. Access more features designed to help businesses thrive

We have already covered some of the ways that VoIP can help your business succeed, however, there are even more helpful features to help streamline business communications.

Some of VoIP’s key features for businesses include:

Which VoIP Software and service provider should I choose?

VoIP systems can be expanded or upgraded seamlessly, however, having the right system in place early on can make the transition between on-premise  PBX phone systems to VoIP much easier in the medium-term. 

Always consider the needs of your business when choosing a partner, and VoIP solution. The benefits of transitioning to VoIP can be unlocked with a reliable internet connection and working with a reputable, trusted VoIP service provider, with a track record for delivering best fit, best-of-breed solutions.

In the not too distant future, half of the world’s connected population will be using collaboration tools. As part of this shift towards an integrated, digital way of working, how we view the phone will also change. Thanks to the growth of Microsoft Teams, Cisco Webex, and Zoom, this has already started to happen.

Considering that the global demand for unified communications as a service (UCaaS) is expected to triple and top $140 billion by 2025, the traditional handset market will be all but dead. As critical mass starts to build in Teams, Webex, Zoom, and others, standards that enable federation between these different platforms will mature and eventually become a reality. What this means in layman’s terms is that a user will be able to instant message, video call, or see presence information regardless of the platform they use.

Even IP-based business phone systems like cloud PBX services will eventually be gobbled up by UCaaS providers. This is due to fewer people making extension calls or using the functionality of the PBX in a distributed working environment despite it being integrated into the UCaaS platform. The disruption resulting from the COVID-19 pandemic has and will still kill many industries within the telecommunications space.

Changing tides

In fact, unified communications will become one of the most important sectors in this changing new environment. Already, we are seeing Microsoft Teams dominating the market share in South Africa.

While this does not mean Webex and Zoom are irrelevant, they simply do not have the market reach and brand awareness of Microsoft in this geography.

Increasingly, people will make and receive calls from inside these platforms. This more integrated environment offers significant advantages to having separate devices (like IP-based business phones).

Licensing channel

Moreover, this will result in local service providers needing to shift their operating models.

No longer able to purely rely on hardware, cloud PABX, and voice minutes, they must begin to investigate the licensing model with Microsoft and other vendors. The reality is that resellers will start losing out on their seat licenses and need to make up for it using other means.

For customers, the transition should be a smooth one. If anything, things will become even more integrated for them with calling, messaging, collaboration, and everything in between available from within their application environments.

Direct routing (the dial pad in the app) is the way to go if operations are going to be future-proofed for any external factors driving change in the telecommunications market.

And while businesses and vendors are adjusting to more integrated, and seamless communications, at speed, service providers cannot continue to operate the same way. It is time for them to not only reinvent themselves, but also how they provide communication services. Change is inevitable, or they face the risk of becoming obsolete in a rapidly changing communications landscape.

You might have heard about a mobile APN before, but what really is it and how does it benefit businesses? 

We’ll give you the rundown on exactly what to expect from a mobile APN solution and how it can streamline your business’ communications. 

Let’s find out a little bit more about APN below

In this blog we are going to cover some key APN related topics and themes

• What is an APN and how does it work? 
• 8 Benefits of Mobile APN for Businesses
• How to set up an APN

What does APN stand for? 

APN stands for Access Point Name (APN). 

It is the name given to the gateway between a 3G/LTE/5G mobile network and another computer network, accessing the public internet or virtual private network (VPN). 

It is a unique identifier that allows a connection to the network and identifies the data access services associated with your account. The APN is the exit point from the mobile network operator’s (MNO) 3G/LTE/5G network into either the public internet or a private network.

What is an APN and how does it work?

A mobile APN can deliver a secure connection that creates a private network on a mobile device, protecting information and linking multiple devices together.

This means a business or organisation can manage multiple SIMs, each delivering data connectivity through a private APN to remote workers. The company can set usage caps for employees, and view bandwidth on an application level, for example whether the user is accessing social networks or work-related sites.

Ultimately, a mobile APN can significantly reduce data spend in the organisation as management has an integrated reporting environment with a universal view of how employees use their mobile data. A mobile APN solution can also use prepaid or postpaid data to provide complete budgetary control.

Types of APNs

There are a few types of APNs businesses might implement depending on their communication needs. 

With the right type of APN, it’s possible to streamline communications and provide an enterprise with an array of benefits. 

Public APN Network

• Shared Firewall
• Firewall lite

A Public APN provides mobile internet access, allowing your mobile workforce to connect to the internet, on common ports and protocols. 

With Saicom’s Public APN solution, IP addresses are allocated either statically or dynamically, and traffic is routed out to the internet via a centralised Firewall. 

Here is how Saicom’s public APN works:

Private APN (also known as a Corporate APN)

A private APN provides clients with a higher level of control and customisation than a public APN solution. 

It  can be likened to implementing a VPN on a mobile network connection. 

With a private APN, businesses can control activities at an application level, and a mobile workforce’s communication is routed using custom  configurations to connect users to a  business’ Head office or data centre (either  via an MPLS or SD-WAN network). 

Traffic might also be routed through a dedicated or shared firewall, or into a data centre or hosting environment.

Learn how a private APN  solution, through Saicom, works below: 

8 Benefits of Mobile APN for Businesses

1. Central management of data usage & budget

A mobile APN solution acts as a way to manage SIMs, carriers, users and departments.

Each device connected to the business’ APN can be analysed to determine usage, from minutes and megabytes used, to understanding which applications are behind the most data usage. 

Analytics are provided via an easy to use  management portal that can also help the business  institute budget control methods. 

 These controls may include setting specific rules for blocking applications and sites, or implementing usage caps for devices. 

Stakeholders can also choose  to receive notifications about data usage percentages throughout the month. 

2. Soft lock and unlock SIMs in real-time 

Administrators are able to soft-lock SIMs and unlock them in real-time. 

A soft lock restricts a device from making outgoing calls but the device can still receive incoming calls. 

This can be useful if a particular device has reached its usage cap, been lost or if a third party is using a specific device.

3. Centralised billing for all users and devices

Monitoring the billing associated with  devices across a large mobile workforce doesn’t have to be stressful. 

From a billing perspective it might appear that one may need to monitor the usage of each individual sim card and therefore handle separate bills for each and every device owned by the business. 

However, this isn’t the case. 

A Mobile APN mitigates the need for complicated billing for a company’s mobile communications and data use. Although devices might have varying sim cards and carriers, each device is connected to a shared, public or private APN. 

A  shared APN allows businesses to monitor and settle the charges associated with the communication and data use across an entire company – streamlining billing management headaches. 

4. Provide devices with specific static IP addresses

Mobile APN solution providers are able to assign specific APN settings. 

Giving company devices static IP addresses is typically one of these options, allowing the business to keep track of the usage associated with specific company devices and their owners. This is crucial for data management and billing purposes, helping the business analyse their data usage in alignment with their budget and informing smarter decisions in the future.

5. Multiple carrier options for reliable connectivity.

A mobile APN solution provides high speed national mobile data coverage (LTE, HSPA+, 3G, 4G and Edge) across a wide range of carriers (including MTN, Vodacom and Telkom). 

With a mobile APN solution businesses can connect devices in remote locations where fIbre and/or ADSL are not available. 

Carrier flexibility can enable mobile workforces to gain the best coverage wherever they are situated. 

6. Protect communications and devices with a selection of security options.

When implementing a mobile APN solution, the business has access to a variety of security options to protect their communications with ease. 

APN solutions are typically public or private – meaning that data is either routed through the Internet using common ports and protocols or using a custom routing configuration that can be used to connect a workforce to its headquarters. It is also possible to select whether the business wants its traffic to be routed through either a shared firewall or a dedicated firewall. 

This customisability allows a business to select just how confidential and secure they would like their communications to be. 

In addition, once a mobile APN solution has been implemented, the business is able to access other security features such as pairing the ICCID of a device to the IMEI number associated with the SIM card – rendering a sim card useless unless used with the correct device.

7. Scalable communications management for large workforces

APN solutions are ideal for businesses of all sizes. 

A mobile APN solution allows you to manage multiple APNs, companies, departments, individuals and their SIMs. 

It’s a no-brainer for large corporate companies with multiple branches, divisions as well as enterprises with hundreds or even thousands of employees and devices

8. Get access to company infrastructure off-site

Implementing a private APN setup can provide employees with access to company infrastructure that is connected to the business’ network.

This could mean providing an employee with access to a private email server, or the ability to view video feeds for the business’ security cameras. 

The business will still be able to control and analyse which devices access parts of the company’s network.

Get started with a mobile APN solution that suits your business’ needs.

So we’ve covered how an APN can offer a wide range of benefits for a business especially with the rise of remote working which has made data security and mobile connectivity an even more essential part of a business’ considerations. 

Setting up an APN solution requires minimal infrastructure and is such a great option for mobile workforces working as part of small, medium or large businesses.

Too Big to Fail (TBTF) is a theory that over time has become synonymous in banking and finance industries. It is built on the tenet, that certain corporations, particularly financial institutions, become so large and so interconnected that their failure would be disastrous to the greater economic system and that they, therefore, must be supported by governments when they face potential failure.

More recently however, we have started to see the emergence of the too large to care theory, in the telecommunications industry. And we find ourselves in the midst of an ongoing battle with many Davids and Goliaths.

For the most part, the Davids of the ICT industry cannot compete with the bottomless budgets that the Goliaths have at their disposal for everything from marketing spend, uncapped operational resources, legal counsel, or inorganic growth strategies.

Even with so much stacked against the Davids, the idea that traditional large companies can’t innovate, and that smaller agile companies will render many of them extinct, is rife. It is clear that large, established tech corporations are being increasingly displaced by small tech companies that are bold enough to use new technologies, develop uncharacteristic solutions, propose against the grain ideology, and deliver left-field blueprints.

Innovate don’t replicate

BYOC, because it is born in the cloud, lends itself to the scalability required for modern organisations. Whether it is a handful of users, or thousands, BYOC and UCaaS deliver the flexibility and functionality needed to scale up or down as necessary.

With more people adopting a hybrid work approach and looking for technology to make them as productive as possible, the pandemic has been the catalyst for UCaaS and BYOC to provide businesses with simplified management for their communication environments.
