Enhanced device administration hindered by complex deployment and security limitations
Cisco Identity Services Engine (ISE) needs to improve the profiling preauthentication. They are very poor in asset classification and should focus on improving the preauthentication profiling, especially for NAC use cases. This will give them a roadmap for software-defined access (SDA) use cases and network segmentation. Threat detection capabilities are very weak. Additionally, the product is vulnerable and has many bugs.
Jordan De Sousa - PeerSpot reviewer
Helped with the consolidation of tools and has a great dashboard
We have used different types of solutions. We had Cisco ASA for about 10 years, and then we switched to an on-site firewall to MX from Meraki, Cisco. For our cloud, we have Cisco Services Routers. The migration to the cloud has been a lot of work. Not all of our systems were compliant with being on the cloud so we had to work on some applications and delete some of them. For the old systems, we had to do extra work but for the newer systems, it was fine. The migration took around 18 months to migrate 99%. We had more than 2,000 on-prem firewall sites. Cisco helped with the migration to the cloud with the migration tool. Migrating MX was really easy and the tools helped us to migrate from the old ASA we had to the new MX. The cloud, firewalling, and CSR helped us from the data center on-premise approach to the cloud because at the time we didn't have a lot of experience with the cloud. It was easy to use the Cisco appliances in that space. I think that this solution has saved our IT staff time because of the ease of deployment. When I first started as a network engineer, it took a whole day to configure a firewall because of all the particularities you could potentially have at a site. I think that this solution saved our organization's time because security saves money because. At the end of the day, firewalls block threats. This solution helped with the consolidation of tools as we had all the observability tools in the solutions. Some 10 years ago we all had third-party solutions doing the observability. Now, we have the whole package and not only the firewall. We choose Cisco 10 or 20 years ago mostly because it was a market-leading solution. I also think it's because of MX's user-friendly solution that you can get on board easily. As far as CSA goes, I believe it's because you have a lot of features on the firewalls and it's the stability of course.

Quotes from Members

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

Pros

"The return on investment we have seen is related to time in terms of troubleshooting. The logs, such as the security logs, inform us of the issues that people have had. ISE has been very instrumental in helping isolate those issues. We've seen a lot of cost savings because we don't have to pay an IT person to waste time doing something that should be instantaneous."
"It offers automatic profiling of phones and computers, enabling administrators to identify and categorize devices seamlessly."
"The ability to integrate our Cisco AnyConnect connections to the active directory has been great."
"We found that the most valuable features associated with this tool are posture assessment, policy management, VLAN assignments, guest assignment, and BYOD services. In addition to these services, the Cisco IOS software switch configuration feature is another very valuable aspect of the policy and compliance solution."
"The access policies, and all of the policies in Cisco ISE, are important to us."
"The profiling model included is the most valuable feature."
"I really enjoy the live log section. Sometimes, you will have someone who is having issues connecting to the network, and then you have to ask them the dreaded question of, "Did you type a password wrong?" They will probably tell you, "No," but the live log can help sort that out. It gives us that extra ability to assist the end user and make sure that we are making them happy."
"SGTs are valuable because they make it easy to enforce policies, instead of pushing them across all the other platforms."
"The most valuable features of Cisco firewalls are the IPS and IDS items. We find them very helpful. Those are the biggest things because we have some odd, custom-made products in our environment. What we've found through their IPS and IDS is that their vulnerability engines have caught things that are near-Zero-day items, inside of our network."
"I think that the firewall feature is the most valuable to me as it is one of the oldest features for this solution. We also appreciate how stable the VPN is."
"The most important feature is its categorization because on the site and social media you are unified in the way they are there."
"Its ability to work with the traffic.​"
"The product is quite robust and durable."
"The firepower sensors have been great; they do a good job of dropping unwanted traffic."
"We have been using a 5520 for seven years in our datacenter and we are satisfied by this version."
"We feel that we can trust the security, and our assets and business are well protected. We need to have trust in it, but we also see that it works. We have a security company that has tested that it works."
 

Cons

"There are still some bugs in ISE that need to be worked out."
"The user interface could be more user-friendly."
"The interface is a little bit complex."
"The pricing and licensing structure are not ideal for customers."
"The price could be better. I would like to see more integration with third-party solutions in the next release. This is because many of my clients don't have Cisco."
"If you have someone taking care of it, it can be quite easy to manage the solution. Otherwise, if you don't look after it and take care of it day-to-day, then it will become more complex to run."
"The admin interface is really slow. It's horrible."
"It is too complex. It should be easy to use. We are not such a big team. We only have three engineers to work with this, and we don't use all of the functionality of the product. Its range of functionality is too wide for us, and this is the reason why we are thinking of switching to a more simple product. We have shortlisted a Microsoft solution. We have a big footprint for Microsoft products, especially in security. As a global strategy, we try to leverage to the maximum what is possible around Microsoft."
"In general, they can make it easier to manage the solutions. They can make it easier in terms of administration and provide a single tool for different firewalling solutions. They have different tools to manage different firewalls, such as Firepower or ASA. Sometimes, both are on the same thing. You have ASA with Firepower modules, so you manage some of the things via HTML, and then you manage some of the things via another management tool. It's not seamless."
"Deploying configurations takes longer than it should."
"It seems very clunky and slow. I would like to be able to tune it to be a more efficient product."
"I think they need to review their whole UI because it feels like it was created by a whole bunch of different teams of developers who didn't fully talk to each other. The net policy screen is just a mess. It should look like the firewall policy screen, and they should both act the same, but they don't. I feel like it's two different buildings or programming, who don't talk to each other, and that really annoys me."
"I was just trying to learn how this product actually operates and one thing that I see from internal processing is it does fire-walling and then sends it to the IPS model and any other model that needs to be performed. For example, content checking or filtering will be done in a field processing manner. That is something that causes delays in the network, from a security perspective. That is something that can be improved upon. Palo Alto already has implemented this as a pilot passed processing. So they put the same stream of data across multiple modules at the same time and see if it is giving a positive result by using an XR function. So, something similar can be done in the Cisco Firepower. Instead of single processing or in a sequential manner, they can do something similar to pile processing. Internal function that is something that they can improve upon."
"The relatively new Firepower Threat Defense image (mix of ASA and Sourcefire network security) fills a lot of gaps and features that were missing on ASA."
"The process of procuring modern-day technology within the DOD needs to improve."
"Cisco ASA is not a next-generation firewall product."
 

Pricing and Cost Advice

"Its price is probably good if you use all of its features and functionalities to protect your environment. If you use only a part of the functionality, its price is too high. It is just a question of value and the functionality you use."
"The price of Cisco ISE (Identity Services Engine) is expensive and we are thinking about changing to FortiGate."
"Hardware appliances are expensive...Now moving to DNA-styled licensing, we have subscription-based licensing for everything. I hope it will continue to be fair, but we will have to wait and see."
"The recent changes in the licensing model have caused some issues with the team."
"We are running Version 2.9 because Version 2.9 of the ISE has a persistent license — it's a one-time payment. The latest version (3.1) is only available if you do a yearly subscription."
"I am not aware of the current price for Cisco ISE, but considering it is a Cisco product, it is likely to be quite high."
"Over the years, licensing has been confusing and complicated because there are so many different licenses for each different product and each different iteration of the product."
"There are other cheaper options available."
"I wish there was an easier way to license the product in closed environments. I have worked in a number of closed environments, then it is a lot of head scratching. I know that we could put servers in these networks and that would help with the licensing. I have never been in a situation where we connected multiple networks, i.e., having an external network as well as an internal network, as those kinds of solutions are not always the best. I think licensing is always a headache for everyone, and I don't know if there is a simple solution."
"I am not a huge fan of Cisco licensing in general."
"In the past, I encountered several difficulties and misunderstandings with Cisco licensing, but now the situation has improved. The Cisco Smart Software portal is an excellent resource for keeping track of, upgrading, and researching information related to Smart Licensing and other relevant topics. It is extremely helpful. Unfortunately, since it is not my money and there is only one vendor, I am unable to provide any comments on the prices. Nevertheless, the system, along with its provision through the Cisco Smart Software portal, as well as the traditional license and subscription models, are excellent and highly beneficial."
"The price is fair. It's not the cheapest, but it's not bad."
"It's a brilliant firewall, and the fact that it comes with a perpetual license really does go far in terms of helping the organization in not having to deal with those costs on an annual basis. That is a pain point when it comes to services like the ones we have on Fortigate. That's where we really give Cisco firewalls the thumbs up."
"Cisco smart licensing is a hassle for a disconnected environment."
"They have a lot of different models but most of them are really expensive."
"​Price point is too high for features and throughput available.​"

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
