Cisco ASA's are great for internal network connected access between a firewall and the central management server. And, for complex networks where high security requirements with overly strict compliance are necessary. For networks with limited connectivity to the core or for poor network connectivity these are not the best solution. There are other more stand-alone firewall's that do this better. These firewall's are a little more complex to set up to start with so significant knowledge of these devices is required to set them up and ensure they are best practice installed.

Zscaler is suitable for all organisations as the internet traffic can be managed very well without any concern. All the devices can be available under a single umbrella, which is easier to manage. The application can be managed via a console, but installation can only be done with the help of a dedicated crew as it needs a one-time password.

Pros
Cisco
  • ASA is our VPN concentrator. The client and server are very stable and very easy to use
  • ASA also offers Intrusion Prevention, to an extent. This is also very useful for an improved security posture for a small company
  • ASA allowed us to scale very quickly. We could onboard clients, partners, and consultants and give them a great onboarding experience as well
  • Administrative costs with ASA are low. It's very easy to administer.

Cons
Cisco
  • The ASDM software is at times a nightmare to install because of different java versions[.]
  • [The firewall] could do with a power button, just to be able to do a hard reboot when needed[.]
  • It would be nice to manage the firewall via the web on port 443[.]

  • Given all of the features Zscaler Internet Access bundles (firewall, CASB, URL filter, DLP, etc...) it makes the console somewhat cumbersome. Anyone planning to utilize Zscaler Internet Access should be prepared to invest time in training or seek out professional services.
  • In some cases, the app risk index ratings do not include enough criteria to effectively assess an applications risk exposure. Adding more criteria or allowing customers to add their own would be a welcomed feature.

To be honest there has been now great products out in the market compared to Cisco ASA. I beleieve Cisco has to do a lot of improvement in this area. The other defeiniete factors is the cost when it comes to renewals which is always a premium on Cisco products

Zscaler
Zscaler is a mandatory solution required by almost every large organization with a workforce working remotely or using cloud-based apps. Its deployment is relatively easy and it keeps on working in the background without actively bothering the user. Apart from a few weird messages which a user is unable to comprehend, Zscaler is able to provide fast and safe access to the internet and other external applications.

Reliability and Availability
Cisco
I generally have not noticed the outages, however since it's a machine it can malfunction, we need to implement the firewall infrastructure in such a way that it is highly available with device failure, region failure etc. Else any solution will be having the issues if they are not build with resiliency.

Support Rating

The support is usually very good and gets back to you very quickly. However I had some instances of when two engineers will give me wildly different answers to what I thought was a simple question. Overall however I do rate the support highly and they are generally always very good.

I cannot give a fair rating for this as I have not had to contact Zscaler support. There was one time we had to contact them because we needed to check if they were having issues on their end. Our ISP was actually the problem but support seemed very friendly.

Implementation Rating
Cisco
It was quite a good one, how ever requires an expertise to deploy hence the SMB segment would be finding it difficult to implement this product. The one good reason is that there are lot of ASA certified engineers in compared to the other certified engineers. Hence this resembles positively on the deployment as you have quite a lot of experienced engineer on your deployment

We were using [pfSense] before in our environment but we regularly facing difficulties over it due to software bugs & downtime. After implementing Cisco ASA, it resolved our availability issue & provides us a reliable solution with the best security features & easy to understand GUI.

Zscaler
Zscaler Intenet Access outperformed the competition due to its lightning-fast policy delivery and cross-compatibility. It is easy to track employee usage and block unnecessary websites, reducing company internet usage. Zscalar installed on every system increases cloud-based software bandwidth, decreasing user turnaround time and increasing efficiency.

Return on Investment
Cisco
  • Most network engineers have worked with ASA, so there is no need for re-training when adding or turning over staff
  • Current configs from older devices plug in easily, and are operational on larger devices if an upgrade is required
  • Many support options available

Zscaler
  • We cancelled our lease line contract and our static IP contract from our ISP which is a key win for us.
  • We can make sure that our users are connecting to our share drive securely even if they are on the road which is also a key win.
  • The negative side with Zscaler is we cant choose our internet gateway IP address as its managed by Zscaler.
  • Another negative side is Zscaler is not a complete package for us as we maintain our on-premise firewall (Fortinet) along with Zscaler.
