Quality Control Manager National Support Team

It's Simplicity of use to the user, great tool for vulnerability scanning for any enterprise. The reports are detailed and easy to understand.

Director

This is one of the best value for money network scanner out there.

Nessus is still the industry leader in this arena, and the ability for the product to identify vulnerabilities accurately is still the high water mark to beat.

The software can be difficult to use sometimes and it doesn't always scan with the credentials needed to have compliant scans.

Network and System Administrator

There is also a very active community on their forums. Reporting is very informative, and scheduling makes it so you don't have to interact much after everything is all set.

Operations Engineer

The most perceptive Vulnerability Scanning Software.

Orca Security

Web-based

Orca's ability to secure out cloud assets has been just amazing and I will keep using this.

Senior Security Engineer

Support - Wonderful support and leadership team that cares about their customers. Open API - Rich and open API that allows you to extend and build on top of the product.

Cyber Security Lead

The Orca UI is clean and provides a good overview, the alerts are relevant, and the export functionality is very useful.

Ciso

Very innovative and responsive team, enjoy working with them to improve the product.

Security Program Manager

I really like how simple it was to deploy across the teams and our infrastructure as it is agent-less. It helps me prioritize effectively and shows me areas that need immediate attention.

Senior Application Security Engineer

Orca provides an excellent way of producing an inventory of assets - particularly useful for ephemeral assets that are perpetually being created and destroyed.

Security Engineer II

Without it, we wouldn't have been able to triage log4j, see malware in our environments, investigate vulnerable cloud instances, and a range of other basic but tricky cloud problems.

Overall our experience with Orca has been great and their support team is really on top of their game.

Agentless was a very big win for me. And now with API scanning, it goes to the next level.

Information Security Engineer

Wonderful, they quickly identify vulns and we are able to easily generate Jira tickets to get them assigned to the people that can fix them.

Lack of on-prem/legacy scanning is a real bummer.

Easy to use/configure, great insights and automated remediation.

Modern graphical interface. Great customer support and onboarding.

Sometimes is hard to find the information you need, it's not because of all the data available but it's not available in the GUI.

Director of Cloud Security

Deploying cloud scanners is a hassle as is agents and we had no visibility into our containers. This product provided all of that in the much coveted "single pane of glass.

Product Security Engineer

Continual solution improvement included in the pricing. Single pane of glass visibility into your Cloud infrastructure with a powerful query language and automation features.

Their dashboards provide an intuitive, easy to digest view of the current state of application security without being swamped by alerts and information.
