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

"The hardware is pretty stable. It's also a very good product performance-wise. Initially, it wasn't mature like a firewall and there were other leaders, but now they have included almost all the features of next-generation security. Basically, it's a good product to work with."
"We are using Cisco IOS Security for endpoint security, for example, spyware, firewall, database and application protection."
"The solution is very user-friendly and easy to deal with, and we find working with both the Command-Line and the Viewer very, very straightforward."
"One of the main features is that the hardware is extremely reliable."
"Previously, anyone in the organization would see any data point in the wall. They could just go and connect their machine with that data point and could access the network. But now, even if someone came and tried that, they will not be given access."
"The scalability of Cisco IOS Security is good; it's very fast."
"The most valuable features of Cisco IOS Security are the plenty of functionality it provides, many people are IT certified in the usage, and the user interface is good."
"The VPN is the most valuable feature."
"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."
"The product's most valuable feature is complete SSL inspection."
"The initial setup is straightforward and easy in comparison with other solutions."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
"The initial setup process is easy."
 

Cons

"I would love it if it has a link-by-link feature, integration with Unified Threat Management (UTM), and load balancers. They haven't got any link-by-link feature right now, which can be a very attractive option. This link-by-link feature can also be made available for Cisco's UTM firewalls. The link-by-link feature is available in some of the other firewalls. Currently, integration with UTM is missing. Cisco IOS Security also doesn't have the load balancers and a few things that need to be done to get a good UTM firewall. Normally, other firewalls have UTM. As a next-generation firewall, it's good, but as a UTM, it has to do some work."
"We need to pay for the license and it is expensive."
"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."
"Cisco IOS Security could improve by having more compatibility with other Cisco solutions."
"Cisco is an expensive firewall, so the pricing can be improved."
"I think the user interface for IOS Security needs to be improved."
"The solution is not user friendly and it is hard to manage the GUI interface."
"Pricing can be reduced. I rate the current price for the product a four out of ten."
"There is always room for improvement."
"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."
"We encounter issues sharing IP addresses with other companies using the software."
"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."
 

Pricing and Cost Advice

"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 pricing is average and includes all features with support."
"They have smart licenses that can be provided for one year, two years, three years, five years, and seven years. Alternatively, they have perpetual licenses available."
"It is an expensive solution."
"We need to pay for the license and it is expensive."
"The licenses for this solution are expensive."
"The pricing is expensive."
"You can get a better price if you commit to a longer-term license. Three years, five years, or even seven or ten years will be cheaper than a three-month or one-year term."
"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."
"The product is not affordable for small and medium enterprises."
