Featured Reviews

Danijel Cerovecki - PeerSpot reviewer
Head of Cyber Defense Department and Network Technologies Department at Verso Altima
Have faced challenges in keeping licensing clear and consistent while ensuring reliable network protection
We are a Gold Partner with Cisco. Our customers come from various industries, including service providers, and we target service providers and enterprise customers.We do not extensively use Zone-Based Firewalls in Cisco IOS Security, instead typically deploying standalone firewalls such as Cisco FTDs or Cisco ASA devices. For threat analytics and vulnerability scanning, we utilize third-party vendors with dedicated devices and software. We use products such as Tenable from Nessus for this type of analysis. We have implemented Secure Access Control Server in Cisco IOS Security, which combines multiple security mechanisms including AAA, 802.1X for network access control with Cisco ICE, TrustSec for identity-based segmentation, and Cisco DNA Center. Cisco IOS Security's VPN support is comprehensive and increasingly important in daily communication, from basic site-to-site tunnels to remote access VPNs and SD-WAN secure VPNs. Protecting and encrypting communication is essential in modern networks. The challenges with Cisco IOS Security are more operational than product-related. There is an understaffing issue, making automation and orchestration capabilities particularly valuable. For the products themselves, we only encounter routine operational matters such as addressing new vulnerabilities and patching. For those considering Cisco IOS Security, it is important to understand that Cisco offers a complete ecosystem. When embracing the Cisco ecosystem fully, customers receive excellent products and comprehensive solutions. On a scale of 1-10, I rate Cisco IOS Security a 9.

Project Engineer at IT Solution
Robust protection has blocked external threats and provides clear visibility into user activity
Sophos Firewall offers multiple features, including IPS, IDS, ATP, NDR, XOps, web protection, application protection, web server protection, and many more. Out of all those features, I find web protection and application protection to be very helpful and valuable in my daily work. Sophos Firewall has positively impacted my organization by preventing outside threats, allowing me to easily monitor my users, and configuring any rule for any user regarding what they need to use and what I am restricting for the particular user. I can share that it has improved productivity because if anyone could ransom my network, they could demand money to decrypt the files, thus saving us money, time, and providing reliability.
