IP Network Security Specialist at MTN Ghana
Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.
Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

Secure access has unified zero trust and web protection while AI assistance automates tasks
From a feature perspective, I have not experienced any issues, drawbacks, or shortcomings. However, the cost of Cisco's products and licensing is high. My clients usually prefer cheaper options if possible. Mid-size or smaller businesses typically cannot afford Cisco Secure Access. Additionally, there is a steep learning curve, as it is very intensive. Someone with significant knowledge can work on it, but a new professional would have to spend considerable time to get accustomed to it. It is hard to find engineers who can work on it. Overall, we get what we pay for, as it is a pretty good feature and service. The pricing of Cisco's products and licensing is higher than competitors. If they could be more reasonable, that would help. The support offered for two years also has higher costs. Overall, the client's IT budget gets affected. It was challenging to learn because, as mentioned, it has a significant learning curve and requires considerable training to become proficient.

Has provided strong traffic visibility and efficient policy management for advanced network environments
Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
