It is scalable and is a very effective solution in that regard. You can size it differently according to your needs, as there are various models available. When it comes to scalability, we address five key factors.

It was very stable. We enjoyed working with it. What we liked best about the WSA was the ability to block uncategorized traffic. 

Uncategorized is usually where you'll find your zero-day issues. A brand new website from a bad actor or bad country is unlikely to be categorized in the Cisco URL database, so we chose to block it. 

There are advantages and disadvantages to blocking that. If you block that, you are blocking a lot of things, and it becomes more of an administrative headache.

As long as you start using this Cisco WAS, URL reporting system, then there is a way around that. Because you could submit this URL we believe is business and whatever, or marketing.

Outside of that, you had to create a white list, which we were able to do due to our flexibility. If something was quick, this is an emergency, this is a valid site, it's not malware, it's not bad, you can add it to that list in your text file.

The virtual appliance is very easy to implement and is stable with no crashes. 

Power outages may affect the hardware appliance because its hard disk is encrypted. 

I rate the solution's stability an eight out of ten because it's used 24/7 in my organization.

The customer prior to where I configured the physical appliance, never complained about it not working. It's been three years or so and it's still operating as smoothly as it operated on the first day. There weren't any breakdowns or lags or anything like that.

The product is stable. I have not seen any issues in five years. We have not had any unintentional reboots or downtime. It is very reliable and is a stable product.

The solution is stable. 

Stability-wise, I rate the solution an eight out of ten.

Cisco Web Security Appliance's stability is good. 

The solution is stable and has high availability.

I rate the stability of Cisco Web Security Appliance a nine out of ten.

Cisco Web Security Appliance is a stable solution.

The stability of this product is very good.

We've been running the latest solution for eight months now and it is totally stable. There are no bugs or glitches and it doesn't crash or freeze. It's reliable. 

Cisco Web Appliance is highly stable if configured correctly. 

It's very stable. We have thousands of users and they don't have any issues with it. It's very stable.

If you want this product to be stable you have to put it through the EPS and you have to manage the connection to the power. If you shut down the product, there will be a problem because they encrypt the discs and you'll have hardware loss. The solution won't work. 

The stability is lacking and is something that should be looked at. We don't find it to be very stable.

We have not faced any issues with stability. 

Cisco Web Security Appliance is stable. Very recently we deployed corporate-wide security practices with all the Cisco devices like Cisco Firepower, Cisco AMP, Cisco Cloud Email Security, Umbrella, and so on and so forth. That infrastructure is running quite okay for the last two to two and a half years. So I must say that all the security products are quite stable in nature.

We have 500 users using this solution. 

This solution is stable.

It is a very stable solution.

The solution itself is stable, but it all depends on the infrastructure of the end-user, and how to integrate the product to the end-user.

It really depends on the complexity of the infrastructure and the design.
