Firewall
Having the right preventative measures in place is a critical first line of defence for your business. But with so many security products in the market, it can be difficult to choose the right ones. Luckily, next generation firewalls consolidate security services so that you don’t have to.
Some of our benefits:
- Access to Saicom engineers
- Trusted firewall solutions
- Assistance with compliance such as PoPI and PCI

Attacks and security breaches are no longer a matter of if, but rather when.
Firewalls act as a gateway between the public Internet and your private network. Not only do they perform basic network functions like routing and network address translation, they also provide more advanced features like unified threat management, web filtering, application control, and intrusion prevention.
The Saicom Security solution is more than just a product; it’s a fully-managed solution to mitigate risk through a policy-driven network segmentation strategy. Delivered either onsite or in the cloud, we use Fortinet Fortigate as our preferred next-generation firewall solution. Providing everything from high-performance threat protection to continuous, automated risk assessment and enterprise-class security management, you can rest assured that your security is our top priority.
Key Features
Frequently Asked Questions
What is a firewall?
Firewalls are security systems that act as a gateway between the public internet and your private network. Not only do they perform basic network functions like routing and network address translation, but they also provide more advanced features like unified threat management, Web filtering, application control, and intrusion prevention.
In the past, firewalls used to be physical devices. However, these have gradually been replaced by software-driven solutions that filter traffic and block outsiders from gaining unauthorised access to sensitive data and devices on corporate or home networks.
What is the difference between an intrusion detection service and a firewall?
An intrusion detection service (IDS) monitors network traffic and identifies patterns of activity. If it detects something suspicious, it will assume the network is under attack and send out an alert. Essentially, it inspects all inbound and outbound network activity, against a list of preconfigured signatures, and acts as a security check on all transactions that take place in and out of the system.
A firewall performs actions such as the blocking and filtering of incoming and outgoing traffic based on a set of pre-configured rules.
What is an Intrusion Protection System (IPS)?
An Intrusion Prevention System (IPS) is a threat prevention / network security technology that examines network traffic flows to detect and prevent known vulnerability exploits. The IPS often sits directly behind the packet filtering firewall and provides a complementary layer of analysis that negatively selects for dangerous content. Like an IDS, an IPS is also based on signature (pattern) matching.
Which is better - IDS or IPS?
The two technologies are quite different in what their intended use is. IDS can only monitor the packets data packets and check them against a database of known threats. IPS can scan the data packets and prevent the delivery of the packet to the network.
Both IDS and IPS detect signatures, which are static templates of known attack patterns. IPS’s download new signatures from vendors daily to gather attack signatures; anonymise and aggregate.
How does a firewall know what to block?
Firewalls inspect data packets against an internal list of rules. These can include the likes of IP addresses (where it filters outside traffic from suspicious IPs) and domain names (where it blocks incoming traffic from known malicious domains).
What is the difference between a hardware and software firewall?
Beyond the obvious, a hardware firewall is installed between the network and the internet and provides comprehensive protection against outside threats. However, these are difficult to install requiring expert IT staff to do so.
Software firewalls are more user-friendly to install, as no physical devices or cabling are required. They can be installed on existing virtualised infrastructure, minimising the time, effort and maintenance requirement to provide the organisation with a complete customisable firewall configuration which can also protect on a per-device or per-application level.
Because a hardware firewall can be seen as a perimeter fence, if it is breached the entire network is compromised while a software firewall protects devices and applications individually.
What differentiates Saicom from other firewall solutions?
Saicom delivers a fully-managed security solution to mitigate risk through a policy-driven network segmentation strategy. Delivered either onsite or in the cloud, we use Fortinet Fortigate as our preferred next-generation firewall service.
As such, you have access to everything from high-performance threat protection to continuous, automated risk assessment and enterprise-class security management. You can rest assured that your security is our top priority.
