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.

Logging and customizable rules have helped improve threat monitoring and detection

The logging is mainly what I consider one of the best features with Cisco Sourcefire SNORT. Being able to log and store it in a file allows you to push it to a centralized repository. The logging and reporting help improve incident response. You should always be logging threats, any sort of misconfiguration, and anything that could be an issue. It's important to at least log and monitor it. The basic rules provide a good baseline in assessing Cisco Sourcefire SNORT's ability in providing real-time analytics for threat detection, but as a professional, you should look to constantly modify that baseline. They provide extensive customizability so you can define your own rules. The customizability allows it to be adaptable in protecting against diverse network threats to the constant change.

Quotes from Members

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

Pros

"I recommend Cisco IOS Security for other organizations."

"Using Cisco also improves the security mechanism of all devices from end to end."

"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."

"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 security is very good."

"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."

"The solution's most valuable aspect is that it is extremely integrated, basically coming with firewall features including IPS, URL filtering, malware, et cetera, offering a good mix of robust, premium features that you can always expand with additional modules as needed."

"You can forget about it, it's going to work unless the hardware fails."

More Cisco IOS Security pros

"With Cisco Sourcefire SNORT, we've been able to prevent and detect intrusion in our network and actually decrease our SLA (Service Level Agreement)."

"There are a lot of features that I really appreciate with Firepower, which is why I advise most of my customers to go with Firepower."

"It is quite an intelligent product."

"If you compare it to other vendors, the technical support from Cisco is excellent."

"I would recommend this solution; it's reliable and scalable, with easy installation and integration."

"Cisco Sourcefire SNORT is easy to configure and the reporting is great. It's also very user-friendly."

"Cisco technical support is unbeatable. It offers a premium service every time."

"The tool's most valuable feature is threat detection, which is important because we have multiple layers not only in Cisco."

More Cisco Sourcefire SNORT pros

Cons

"It's a good device yet it's not a market leader. There are better options for customers to choose from."

"There's a technology called SD-WAN that we would like to see. We are unable to handle multiple connections or to automatically load balance. I would like to have a feature that enables us to automatically prepare for load balancing."

"Cisco IOS Security's monitoring is rather rudimentary and could be improved."

"The configuration should be easier in the solution."

"The whole process can be complex."

"Some additional features could be improved. For example, the licensing for DNA environments could be better."

"In the next release of this solution, we would like to see support for the 100BT and 7000 models."

"The solution’s setup process could be better."

More Cisco IOS Security cons

"While the alerts they offer are good, it could improve it in the sense that they should be more detailed to make the alerts more useful to us in general. Sometimes the solution will offer up false positives. Due to the fact that the alerts aren't detailed, we have to go dig around to see why is it being blocked. The solution would be infinitely better if there was just a bit more detail in the alert information and logging we receive."

"There are problems setting up VPNs for some regions."

"Sometimes the solution will offer up false positives."

"The price of this solution could be improved."

"To be frank, the product is not really stable, although they're working on that. Whenever I go to the technical community with an issue, they will usually say that it is not there yet, but the technical team are working on it. The issues are not insolvable. I think they should just keep working on the product to make sure that the product can become very stable. The technical support is great. I appreciate that. We have a lot of communities supporting Firepower now, so you can find help for whatever issue you have."

"The initial setup is a little difficult compared to other products in the market. It depends on the environment. If we are doing any migration, it might take months in a brown-field environment."

"The main dashboard of Cisco Sourcefire SNORT could improve."

"There are some bugs in this solution and troubleshooting them is complicated."

More Cisco Sourcefire SNORT cons

Pricing and Cost Advice

"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 solution's pricing is very good."

"The tool could be priced lower. If you want advanced services, then you need to purchase them."

"The product is expensive."

"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 expensive."

"The licenses for this solution are expensive."

"The price of the solution should be cheaper, and the license is purchase annually."

More Cisco IOS Security pricing and cost advice

"We have a three-year license for this solution."

"If one is an extremely expensive product, and ten is cheap, I rate the tool's price as a five."

"Licensing for this solution is paid on a yearly basis."

"I don't know the exact amount, but most of the time when I go to a company with a proposition, they will say, "This thing that you are selling is good, but it's expensive. Why don't you propose something like FortiGate, Check Point, or Palo Alto?" Cisco device are expensive compared to other devices."

"The cost is per port and can be expensive but it does include training and support for three years."
