Likelihood to Recommend

Nessus

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.

Zscaler Internet Access

Zscaler is suited for organizations where a lot of employees work remotely and need to access a lot of cloud-based applications. It enables an organization to filter out content and applications that don't adhere to policies. It provides a scalable on-demand solution with over 150 data centers to allow users to have low latency in connection.

Zscaler Internet Access

  • Securing third party access is a bit complex to implement. These are our third party partners who require access to our data center on a temporary basis.
  • It is a bit of a learning curve to transform from the VPN and appliance architecture to this model.

It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.

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.

While overall support was always nice and polite, most of the time it was hard to reach them and it took awhile for them to respond back in urgent cases. It was probably an isolated case but, still, it's hard to manage a tool without proper support from the vendor when in need.

Alternatives Considered

Nessus

Tools like Qualys, Rapid7 stack up well against Nessus, but I think Nessus is superior overall when compared to them, given the features it has.
Tejas Gandhi | TrustRadius Reviewer

Zscaler Internet Access

I have previously used Websense and Bluecoat, both with mixed results. Zscaler is the superior product if for no other reason that is far easier to deploy and manage
