Red teaming companies: compared, with sources

Red teaming companies sell a different thing from pentest firms, though many sell both. A red team exercise has an objective, such as reaching a data store, and measures whether your people and tools notice. The table lists providers whose own pages state red teaming, A to Z and unranked, checked on 9 November 2026.

What does red teaming cover?#

A red team is, in the NIST glossary wording (citing CNSSI 4009-2022), "a group of people authorized and organized to emulate a potential adversary's attack or exploitation capabilities". The aim is to show defenders which measures work in a live setting.

That differs from a pentest, which lists as many weaknesses as it can in a set scope. For the full comparison, read red team vs penetration testing. Many providers also list social engineering and physical testing as part of an exercise. See social engineering testing providers and physical penetration testing providers.

Who needs a red team, and when?#

You need one when basic fixes are in place and you want to test detection and response. Without that, a red team will find easy paths that a pentest would also find, at a higher price. Typical buyers have a security operations team or a managed detection service and want to know if it works.

A test of one web app or API does not need a red team. Start with a scoped pentest and move up when the findings are few.

What should you ask red team providers?#

Settle these seven points in writing before you sign.

NIST SP 800-115 says legal advisors should always be involved in intrusive tests. Have your counsel read the rules of engagement.

What drives the price of red team services?#

Price follows the length of the exercise, the number of operators, the objective, whether physical or social engineering is included, and the retest or purple team option. The "Published price" column shows only prices that a provider lists. Red team work is usually quoted after scoping, so "custom quote" is the normal entry. The penetration testing cost guide has sourced ranges for related work.

How do you read the table?#

The table includes any provider whose pages state red teaming as a service. That is a wide net, so it includes platforms that also sell autonomous or AI-assisted testing. Check the Type and Delivery columns first. A row that says "autonomous testing platform" does not describe a human-led adversary exercise.

Compliance scheme names appear on each provider page, not in this table. Pen Test Partners, for example, lists CBEST and TIBER in its compliance mentions in our dataset. Open the provider page for the source.

What scoping mistakes weaken a red team exercise?#

An objective that is too broad ("find anything") turns the exercise into a pentest. Too many people knowing about it ruins detection testing. Unwritten stop conditions cause arguments when a real alert fires. Finally, no one budgets time to fix findings, so the next exercise repeats the first. Write the objective, the circle of knowledge and the stop conditions before kickoff.
