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

"Cisco IOS allows us to keep the same security features as our principal offices."
"The capabilities for scalability with this product are huge"
"Cisco IOS Security is a mature product with extensive capabilities, serving as the base for the defense layer. It offers good network visibility, which helps in rapid response through the Rapid Threat Containment feature. Its deployment and configuration are straightforward."
"Completely integrates branch offices with perimeter security."
"There is a positive impact on security, particularly the intrusion feature, which helps keep the solution concealed and secure."
"Cisco Technical Assistance Center works on a follow-the-sun concept and gives real 24x7 customer support, which is a great advantage when you have a service contract with them."
"I've found their network routing to be very good."
"Cisco IOS Security is very robust and works very well."
"The initial setup process is easy."
"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."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
"The initial setup is straightforward and easy in comparison with other solutions."
"The product's most valuable feature is complete SSL inspection."
 

Cons

"I wish it would be more like the next generation firewall technology. There should be more selection between the application and filtering."
"The routers, don't have like long-term tendency features, or higher availability features available for the IOS. It could also use a better user interface."
"Cisco changes their licensing policy quite frequently, which is becoming confusing and complicated."
"With respect to user-friendliness, it is a command-line interface and those with such experience will get along just fine, whereas others may struggle."
"The solution is complex and can be more user-friendly."
"The company needs to make its solution more affordable to make it more accessible to larger markets. Otherwise, it's seen as an enterprise-level solution that small or medium-sized organizations can't afford and therefore they won't even look at it."
"If they could increase the performance a little better because the device sometimes gets slow."
"An area for improvement in Cisco IOS Security is the performance because it's not as stable sometimes. There's also some latency in the solution, which could be improved. Cisco IOS Security integrates with other solutions, but you'll encounter many errors after integration, so this is another area for improvement. I'd like to see enhanced performance and a simplified setup in the next version of Cisco IOS Security."
"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."
"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 encounter issues sharing IP addresses with other companies using the software."
 

Pricing and Cost Advice

"The pricing is very expensive. Normally I do a yearly contract; I don't know the exact pricing, but it's around $75,000 USD per year. That's the standard licensing."
"The cost of the license, to the best of my knowledge, is approximately two thousand dollars."
"The tool could be priced lower. If you want advanced services, then you need to purchase them."
"The price of the solution should be cheaper, and the license is purchase annually."
"Cisco IOS Security is not very expensive, and pricing depends on where you live. It's affordable for both individuals and institutions. On a scale from one to five, I would give Cisco's pricing a four."
"It is necessary to pay for a license in order to use the solution. It is on a yearly basis and the price is high."
"The solution's pricing is very good."
"Cisco IOS Security price could be reduced, it is more expensive than many of the other solutions, such as Sophos and Fortinet FortiGate."
"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."
"The software has become more expensive at present."
"The product is not affordable for small and medium enterprises."
