Penetration Testing Companies: Comparing The Top 5 Vendors

If you’ve had a penetration test performed for your business, you likely know that not all pentesting vendors are created equal. It can be difficult to find the best vendor for your specific business type, delivery speed needs, and one whose strengths fit your environment.

This is why I’ve compiled this list of the top penetration testing vendors and what each of their strengths are, who they’re the best fit for, and how fast they can deliver your report.

Read this blog to get the detailed information you need to pick the best pen testing vendor for your unique needs.

Green Flags You Should Look For When Choosing a Pen Test Vendor

Green Flag #1: An In-Depth Scoping Call

Some penetration testing vendors don’t take the initial scoping process seriously, which ends up costing you more money and more time.

Remember, your penetration test is paid for by an allotment of hours or days; you don’t want to eat up that time discussing what should have been discussed in your initial scoping call.

A green flag would be a vendor who asks about where your sensitive data lives so they can prioritize those attack vectors instead of just casting a wide net on your network.

Green Flag #2: Proof of Manual Exploitation

Some penetration testing vendors use clever marketing speech to hide that they actually only offer an automated test (e.g., vulnerability scan). You might be tempted to choose an automated test; they are, after all, much cheaper, but this is because they lack human intelligence and decision-making.

Manual pen testers think creatively, reducing false positives and finding complex business logic flaws.

Automated tools may produce high false positives and miss unique, complex scenarios.

Since your business is up against actual hackers, having a pen tester that knows how they think and what to look for can make a massive difference.

A green flag when choosing a pen testing vendor would be a vendor who isn’t afraid to share past examples (redacted of sensitive information) that show manual exploitation of environments similar to yours.

Green Flag #3: Detailed Remediation Advice and Reporting

Your pen test is only as valuable as the report it produces, so you want to make sure that your vendor gives you all the nitty-gritty details of how they exploited your environment. In addition to how they were exploited, you will want detailed advice on how to fix your vulnerabilities. Screenshots, curl commands, and code snippets can make the whole remediation process much easier for you.

Ask your pentesting vendor for an example of their typical report to make sure it’s as precise as you want. See if they offer a complimentary retest within a 30 to 90-day window, so you can see if you’ve actually improved your security.

A green flag when choosing a pen tester is one who gives comprehensive reports and complementary retests.

Top Penetration Testing Vendors: Pros and Costs

Every pentest vendor is going to have specific things they excel at, and of course, their own pricing model.

It’s important to understand that many vendors offer a credit-based model, meaning they charge by the day. Other vendors that specialize in large and high security environments are less clear about their pricing because they only offer customized quotes.
