Cisco Adaptive Security Appliance (ASA) Software vs. Juniper SRX

We moved our operations entirely to the cloud a few years ago. We loved the stability and scalability of the ASA and wanted to, somehow, keep using it. We discovered that ASA was available in the cloud as well and it was branded ASAv. We tested it and noticed that it was equally robust and a perfect fit for us. During the entire migration period, we used ASAv for cloud operations and put a lot of load on it. ASAv performed very well and gave us an easy transition from on-prem to the cloud.

Juniper vSRX is an excellent edge gateway device. The combination of Tunneling protocols supported and the advanced routing & security features makes it perfect for this kind of deployment. It is available in physical, virtual appliances as well as support on multiple clouds so you can have the same box be your edge gateway in multiple environments for consistency.

It can also work as a Internet Gateway, DMZ Firewall/Router and it would function just fine.

While it can also work as a DC firewall (North-South), the poor GUI will make it harder in the day to day administration for the multiple policies in a DC.

• How we can manage: ASDM the GUI is so much easier to manage it even for a new guy also.
• Traffic handling capacity
• More secure and the different features it gives.
• Support from the TAC team or from the community manages to handle issues very efficiently.

Incentivized

• The Juniper SRX platform is easy to set up (out of the box).
• The support team responds to tickets quickly and with good solutions.

Incentivized

• The Java based ASDM can botch commands and isn't compatible on some more locked down systems.
• Monitoring. Really the same complaint as above, the monitoring available through the ASDM is crappy at best. A much better solution is to send the logs and mirror packets to a SEIM, but that can create issues of its own when looking for realtime analysis.
• Compatibility across other ASA models. ASA 5520s don't play well with 5525X which don't play well with older 5510s. Each is great on it's own, but it's next to impossible to logically stack them or have them as layers of firewalls in an infrastructure.
• Lack of cloud based management. The Cisco Meraki security devices do this well, but the ASAs are still behind in this regard.

Incentivized

• Some of the more complex setups (clustered HA, etc.) can be a little difficult to configure.
• The lowest-end model that supports true multi-site HA is relatively expensive. It would be nice to have that option in lower models.
• Some configuration options (particularly the way address book entries are done) can get tedious and make for very long configs.

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

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.

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.

This is the one area where I have a beef with Juniper. When I called into Cisco TAC, 90% of the time, the first person I spoke with was able to resolve my issue. With Juniper TAC, 90% of the time, the first person I speak with is not able to resolve my issue, seems to almost be reading from a script, and must escalate my ticket. All of which takes time.

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

Cisco has made it easy to buy, set up, and manage all of our firewalls with the central FirePower Management Center. All licensing is done via one license portal too. Tech support is standardized for all ASA devices and like support engineers who know the different models to provide timely help for any issues. Cisco Talos is a premier could platform which scours the internet looking for threats and develops protections for the ASA's and as such provides zero second coverage when it best can detect global issues.

Equipment prices ran about the same. Performance and management were also more or less equal. The biggest deciding factors for going with Juniper were (1) fewer security incidents related to SRX firewalls and (2) technical support costs were significantly less.

Incentivized

• I know a customer who is still using a Pix[.]
• The 5510 is still being used in one of our setups, and still doing its job this is a lot of Return on Investment.
• We have managed to turn around projects quickly because most of our engineers understand this firewall very well. We deploy them in a matter of minutes[.]

Incentivized

• It is a workhorse for our field operations. It provides the last touch for an ISP to the customer. The customer has no view of the device, but with the repeatability of the device, they do not need to.
• The ability to roll out a dynamic routing protocol attached to a security zone allows elasticity to the environment that supports growth.
• VLAN support on the inside interfaces allow this to be the only device in some smaller deployments we install these in.
