It's a reliable solution that will be around for a long time, but the configuration and reporting interfaces need improvement
Pros and Cons
- "The VPN was valuable for us because more people are working from home. It has a lot of reporting and easy-to-use management tools."
- "The configuration and reporting interfaces need a lot of improvement. It needs to be more accessible forsolide without a strong technical background. If you had a simplified dashboard, the lower-level techs could manage the solution and provide services. Cisco IOS Security requires someone who is highly trained to operate it."
What is our primary use case?
What is most valuable?
The VPN was valuable for us because more people are working from home. It has a lot of reporting and easy-to-use management tools.
What needs improvement?
The configuration and reporting interfaces need a lot of improvement. It needs to be more accessible forsolide without a strong technical background. If you had a simplified dashboard, the lower-level techs could manage the solution and provide services. Cisco IOS Security requires someone who is highly trained to operate it.
There is central management, but reporting could be more centralized too. You can have a lab module. However, we need to see some es, and that will help you deploy without breaking the live system. There's no way for me to have a live system to test my new configuration. If it breaks, I have to deploy it and reverse it to the previous configuration.
It would be nice if I could create an online lab on the fly to test for 10 minutes to an hour without messing anything up. That would be great, especially for things that we do on our live network appliance.
For how long have I used the solution?
I've been using Cisco since the late 90s.

881,757 professionals have used our research since 2012.
What do I think about the stability of the solution?
The stability is great. It takes a bit of time for them to introduce new features that I want.
What do I think about the scalability of the solution?
All Cisco products are scalable. The scalability is there, but the pricing model isn't straightforward.
How are customer service and support?
I rate Cisco support four out of 10. Dealing with Cisco support is complicated. First, there's a time difference because we are in the GMT+2 time zone. It sometimes takes a while for your ticket to be assigned. Today, I find that other cloud service providers respond much quicker than Cisco, even though they are smaller. They need to improve on response time.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
It was the first solution I've used, and I've stuck with it because I'm comfortable with it. I haven't used other products, but I'm evaluating some because Cisco is becoming more complicated in terms of licensing, features, and other stuff.
How was the initial setup?
I wouldn't say the deployment was complicated, but I wouldn't use the word "easy" either. It's straightforward if you know what you're doing. However, it can be complicated if you don't know what you're trying to do. You need a bit of training before touching it. By contrast, FortiGate is easier to get started, but Cisco solutions require training before you start messing with them.
It wasn't much of a challenge for me because I've been working with Cisco for a while. Initially, there were some painful moments where you thought these things would break.
What about the implementation team?
We were doing everything by ourselves at first, but we ended up using an integrator at some point.
What was our ROI?
In IT services, we don't calculate return on investment. It allows the business to grow, so we don't calculate the return. We just look at the IT cost.
What's my experience with pricing, setup cost, and licensing?
I rate IOS Security six out of 10 for pricing
What other advice do I have?
I rate Cisco IOS Security six out of 10. For someone who wants something that works, they can be sure that Cisco will be there in the next five years. Cisco products have longevity because the company is secure, and you know the product will be supported for many years.
There is longevity if you can afford it. At the same time, you'll need to invest in learning the product. The most vital aspect of Cisco is that it works, and the company is there for you. You are sure it'll be there tomorrow.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

We use Cisco IOS Security for integration purposes. We have Cisco features and Cisco devices in our organization. We use it as an integration system for Cisco devices.
What is most valuable?
Cisco products are very secure and integrate easily with other devices.
What needs improvement?
The graphical user interface or the GUI could be better. Beginners can use some devices with the GUI, but some security devices are configured using CLI. It would also be better if it had its own Intrusion Protection Service and Intrusion Detection Service on the server.
For how long have I used the solution?
I have been using Cisco IOS Security for more than three years.
What do I think about the stability of the solution?
Cisco IOS Security has been stable so far.
What do I think about the scalability of the solution?
The device is not scalable because the device was manufactured with a specific product specification. To scale, you have to plan and add more devices. We have about 12,000 users.
How are customer service and support?
They are supportive and have the technical skills to support us. If I have challenges with a Cisco product, they help me based on their subscription fee.
On a scale from one to five, I would give Cisco technical support a five.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is straightforward for IT users. It takes about one hour to implement this solution because we have to upgrade the framework on some of the devices.
On a scale from one to five, I would give the initial setup a five.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
We chose Cisco because the company has an excellent market rating, users are familiar with Cisco, and they can deploy Cisco products. Using Cisco also improves the security mechanism of all devices from end to end.
On a scale from one to ten, I would give Cisco IOS Security an eight.

Secure, cost effective, and easy to install
Pros and Cons
- "It is less expensive than alternative firewalls."
- "While Cisco IOS Security is stable and scalable, I would like to see it improved to be even better."
What is our primary use case?
We can use iOS security for a variety of security features. We can use it to run DPM. We run encrypted data and can use it for zone-based firewalls, to a zone-based firewall.
I use VPN solutions such as site-to-site or user-site VPN, and some do not require a firewall.
What is most valuable?
It is less expensive than alternative firewalls.
What needs improvement?
While Cisco IOS Security is stable and scalable, I would like to see it improved to be even better.
For how long have I used the solution?
I have been working with Cisco IOS Security for three months.
I use version 12.4 and I use 15 and above for the router.
What do I think about the stability of the solution?
Cisco IOS Security is very stable.
What do I think about the scalability of the solution?
Cisco IOS Security is a scalable solution.
We have approximately 50 users.
How are customer service and support?
We have not contacted technical support.
I don't have any critical issues, and I haven't had any open technical tickets with support. Everything is fine, but I work in security with multi-media solutions. We haven't had any problems.
How was the initial setup?
The installation is straightforward. It's easy, we didn't have any problems with the installation of Cisco IOS Security.
I have three or four technical teams to help me work on publishing.
What's my experience with pricing, setup cost, and licensing?
Cisco IOS Security requires a license.
With Cisco, we have a variety of licenses. 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. I am working with a perpetual license, but not a smart license.
What other advice do I have?
Before we can use any security feature on the Cisco router, we must first purchase an iOS security license.
Yes, I would recommend this solution. It is more stable and less expensive than other firewalls. In some cases, it saves money for the project or the companies that work with it.
I would rate Cisco IOS Security an eight out of ten.

IPsec technology allows our clients to be more agile in their connectivity, but the technical support response times should be better
Pros and Cons
- "What I have used the most and received the most benefit from is the IPsec technology."
- "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."
What is our primary use case?
We are a reseller and Cisco IOS Security is one of the network security products that we offer to our clients. The primary use case is securing connectivity between sites. Examples of this are between a site and a data center, or a site and a cloud provider.
How has it helped my organization?
DMVPN as a technology, not necessarily for security, has allowed my customers to be more agile in their connectivity, without having to rely on a hub-and-spoke topology. Rather, they can leverage a full mesh topology, which is essentially SD-WAN.
IPsec allows us to overlay that, which means we can obfuscate the underlying infrastructure, whatever the transports are. Whether it is a secure private transport like MPLS or just public internet, we can commoditize the underlying transports and trust that everything is secured from prying eyes.
What is most valuable?
What I have used the most and received the most benefit from is the IPsec technology. It overlays on DMVPN tunnels and being able to secure these object-based tunnels is good because they perform significantly better than traditional IPsec tunnels.
What needs improvement?
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. My expectation is that it will remain a primarily command-line-based technology.
The biggest annoyance is probably the quality control of the code. They have to make sure that they are better at vetting bugs and software issues before they release code to the general public.
For how long have I used the solution?
I have been working with this product for the past ten years.
What do I think about the stability of the solution?
It is not the most stable system that I have worked with.
What do I think about the scalability of the solution?
I don't think that scalability is much of an issue.
Our clients are small enterprise-level organizations, typically between 1,000 and 5,000 knowledge workers.
How are customer service and technical support?
The technical support is pretty good and I would rate them an eight out of ten. If anything, they should work on their response times for critical cases.
Which solution did I use previously and why did I switch?
I would say that 80% of my experience is with Cisco products.
How was the initial setup?
The initial setup is fairly complex, although it depends on the feature sets that you're looking for. Cisco IOM is probably the most complex part of it because it involves setting up all of the QoS policies, performance-routing policies, and performance-routing domains.
From a DMVPN over IPsec perspective, it is pretty straightforward.
What's my experience with pricing, setup cost, and licensing?
Price is certainly something that the IOS technology has fallen behind the competition on.
What other advice do I have?
My advice for anybody who is implementing this product is to ensure that they don't overlook the technical overhead that is required to get it set up and keep it running. From an SD-WAN perspective, there are more user-friendly options out there, so they are going to have their own shortcomings. However, if you're going down the route of a Cisco command-line-based solution then make sure that you're prepared to have the staff on hand to manage it or instead, have a trusted partner that you work with and has the expertise to manage it.
From a feature-set perspective, as long as Cisco continues down the path of combining features from its products onto the unified platform, it will have all the features you need.
It's a good product and it does exactly what it's intended to do, but there and stability issues and the price is expensive.
I would rate this solution a seven out of ten.

It covers everything but is especially effective when a lot of the traffic is in layer 7
Pros and Cons
- "We are able to filter a lot of traffic especially when a lot of the traffic is in layer 7."
- "It covers everything we need it to without looking to secondary solutions."
- "The user interface needs to be improved."
- "Signatures and other critical definitions need to be updated more frequently."
What is our primary use case?
Our primary use is just as a firewall. That is pretty much it.
How has it helped my organization?
We are able to filter a lot of traffic. The is especially effective when a lot of the traffic is in layer 7 — the internet aspect of security for application services.
What is most valuable?
I think the multi-layered approach is valuable. Just the fact that it covers everything on the LSA (Local Security Authority) right up to layer 7, in-depth packet analysis, and all that. It covers everything we need it to without looking to secondary solutions.
What needs improvement?
I think the user interface for IOS Security needs to be improved.
I think the signature updates and all the other critical definitions need to be updated more frequently.
For how long have I used the solution?
We have only been using IOS (Internetwork Operating System) Security since about 2016. So we have worked with it for about four years.
What do I think about the stability of the solution?
The stability of the product is okay. There were not really any bugs or glitches that I can remember.
What do I think about the scalability of the solution?
The scalability aspect of it is that it is one of those products where you have to incorporate additional hardware. It is a vertical scale, so you add on the boxes you need and bond them together. Of course, it costs more to scale that way than something that would be a software upgrade. You have got to pay to scale and to get more features.
Our clients are generally small to medium-sized businesses. Cisco IOS is a pretty good fit for that range of clients.
How are customer service and technical support?
I have used the Cisco technical support and they were okay. Rating them out of ten, I would give them an eight or nine-out-of-ten. They have a pretty good system with decent response time and accuracy. They are good overall and in comparison to other services. They offer 24/7 service, which is a benefit.
Which solution did I use previously and why did I switch?
I was actually using Cisco products more in the past and use them as a consultant. Right now, Sophos is the only one I have been using. It just came about through one of those situations where we were able to partner up with Sophos. That is really the reason for the change.
How was the initial setup?
Setup and installation are pretty much straightforward. Comparing the installation to Fortinet or Sophos they are all the same.
What's my experience with pricing, setup cost, and licensing?
The pricing for IOS Security is okay. It is competitive. It costs more when you have got the need to pay for more features. You have to buy more boxes and tie them together to upgrade to the next level.
Which other solutions did I evaluate?
I have used Fortinet in the past too as well as Sophos and other Cisco products. They are all similar and if you know how to use them they are virtually all the same.
What other advice do I have?
The advice that I would give to others looking into implementing this product is that I think they need to do their benchmarking. They should do due diligence beforehand in terms of their traffic.
On a scale from one to ten (where one is the worst and ten is the best), I would rate this product overall as about an eight-out-of-ten. I do not know how they could realistically improve on that much. You never keep up with the hackers, they are always a step ahead of us when it comes to security.
