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.

Quotes from Members

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

Pros

"The VPN was valuable for us because more people are working from home, and it has a lot of reporting and easy-to-use management tools."
"Cisco products are very secure and integrate easily with other devices."
"Cisco technical support is the best in the world."
"The product has valuable features for business intelligence."
"Using Cisco also improves the security mechanism of all devices from end to end."
"I've found their network routing to be very good."
"The Intrusion Firewall is a valuable feature."
"In terms of scalability, it definitely suits all enterprise needs; the product is all we need for today's enterprise, for the client, and for me, in terms of scalability, Cisco has the full package."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"Hillstone supports IOT setup and detecting intrusions from IOT or CCTV connectivity, and with this solution, we can also detect unauthorized devices plugged into the CCTV network and sound the alarm to the administrator."
"It has been stable so far."
"We found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
 

Cons

"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 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."
"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."
"I would like upgrading iOS to be a bit easier."
"We cannot directly upgrade the system. The tool's deployment is also very difficult in legacy environments. The tool needs to have bigger ports as well."
"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."
"Cisco changes their licensing policy quite frequently, which is becoming confusing and complicated."
"As it is a tailored solution, it is not very scalable, but this is a trade off; you need a hammer or a scalpel."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"Licensing is not cheap, but there are customers who will buy because they understand that this has a cost involved and they will cater their budget for that."
"Licensing is not cheap."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
 

Pricing and Cost Advice

"The solution's pricing is very good."
"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 cost of the license, to the best of my knowledge, is approximately two thousand dollars."
"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."
"The price of the solution should be cheaper, and the license is purchase annually."
"Price is certainly something that the IOS technology has fallen behind the competition on."
"The pricing is okay. It is competitive. It costs more when you need get more features."
"The licensing is on a subscription basis, and it is fairly costly. I would prefer a one-time payment."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"We got a much cheaper price than that provided by Fortinet right now."
