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.

Stable product with valuable SSL inspection features
We use Zscaler Cloud IPS for threat protection, full SSL inspection, and data center scalability. It integrates with multiple products, including cloud firewalls, cloud sandboxing, Cloud Security Broker (CSB), and Data Loss Prevention (DLP). It helps us allow or block specific TCP or UDP ports…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"You can forget about it, it's going to work unless the hardware fails."
"Cisco products are very secure and integrate easily with other devices."
"EEM is a handy feature if fine tuning of monitoring is required or if you would like to turn a Cisco device into a programmable device without fancy words like ACI or Python, and it is low level but efficient and money saving."
"I'm able to transfer data over internet network security. With the GRE I'm able to transfer data within one bunch to another bunch in a public way, like the internet. The communication is encrypted and is private. It gives me added privacy."
"The VPN connection portal scan works flawlessly, which was a big plus for us."
"Cisco IOS Security has many good features, but compared to other solutions, it has a more user-friendly interface with steps to apply and manage rules. Another good part of the solution is that it's more straightforward."
"What I have used the most and received the most benefit from is the IPsec technology."
"The software offers plenty of security solutions that can work in the most sophisticated enterprise but also works well for small/mid-range enterprises."
"The initial setup process is easy."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
"The product's most valuable feature is complete SSL inspection."
"The initial setup is straightforward and easy in comparison with other solutions."
"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."
 

Cons

"Cisco very slowly introduces and implements the products, unlike other brands."
"Their support was very bad. We have a very bad experience on the support."
"Cisco IOS Security could improve its security features. There are competitors that have some additional security features, such as Fortinet FortiGate. Additionally, there should be better synchronization with Cisco IOS Security and other vendors, and improved AI features would be beneficial."
"Cisco IOS Security should improve its functionalities."
"Cisco changes their licensing policy quite frequently, which is becoming confusing and complicated."
"In the next release of this solution, we would like to see support for the 100BT and 7000 models."
"Signatures and other critical definitions need to be updated more frequently."
"I think setup could be one area for improvement, because sometimes we don't have people inside so we have to move to the place."
"We encounter issues sharing IP addresses with other companies using the software."
"There is always room for improvement."
"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."
"When it comes to scalability, the IPsec could be improved."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
 

Pricing and Cost Advice

"The licensing is on a subscription basis, and it is fairly costly. I would prefer a one-time payment."
"We can purchase its licenses as per specific business requirements."
"Price is certainly something that the IOS technology has fallen behind the competition on."
"The product is expensive."
"The price of the solution should be cheaper, and the license is purchase annually."
"The pricing is average and includes all features with support."
"Palo Alto networks are more expensive than this solution and this is why you will see more products like this one in Mexico."
"The cost may be around $5,000 to $10,000 a year. If you want support you have to pay at least this price."
"The product is not affordable for small and medium enterprises."
"The software has become more expensive at present."
"Zscaler has so far been solely responsible for all the sales we have done with it, so it would be more suited than us to address any issues concerning the pricing."
