Red Team vs Penetration Testing: Which One Do You Need?

The difference in red team vs penetration testing comes down to the question each one answers: a pentest finds which weaknesses in a defined scope can be exploited, while a red team tests whether your defenders can stop a goal-driven attack. Both test your security, but they differ in scope, duration and goal.

The red team vs pentest choice depends on maturity. Start with a pentest for audit evidence or a new system, and add a red team to test monitoring and response.

Penetration testing: what vulnerabilities exist?

A penetration test shows which weaknesses in a set scope an attacker could exploit.

• Question asked: Which weaknesses in this scope can be exploited?
• Scope: A defined target, such as web application testing or network and infrastructure testing.
• Duration: Typically 1 to 3 weeks of testing, plus a few days for the report.
• Visibility: Overt, so your IT team knows the test is running. We report critical findings during the test.
• Goal: Find as many exploitable issues as possible, with step-by-step fixes, as in this sample penetration test report.
• Use case: A security baseline, a check after major changes, or audit evidence for compliance requirements. To set the scope, compare internal vs external penetration testing.
• Our price: Our standard web application or API test costs $2,500–$5,500, and our complex infrastructure or cloud test runs $5,000–$12,000+. A retest is available after fixes.

Red teaming: can your team stop an attack?

A red team plays a real attacker pursuing an agreed objective to see whether your defenders notice and respond. A red team assessment measures response, not the number of flaws.

• Question asked: Can an attacker reach a goal without being stopped?
• Scope: Built around an objective, not a list of systems. Social engineering can be added to the scope and is quoted individually.
• Duration: Scoped per engagement. Under DORA, the active red team phase of a TLPT lasts at least 12 weeks (Commission Delegated Regulation (EU) 2025/1190).
• Visibility: Covert, with objectives agreed with a small group. NIST SP 800-115 describes covert testing as done “without the knowledge of the organization’s IT staff” but “with the full knowledge and permission of upper management.”
• Goal: Reach the agreed objective and show where detection or escalation breaks down.
• Use case: Teams that already fix pentest findings and want to measure their response.
• Our price: Our red teaming service starts from $15,000, and a full DORA TLPT is quoted individually. Compare our penetration testing pricing.

In red team exercises run without social engineering, we’ve seen a security team receive an alert about unusual activity that triage didn’t initially classify as part of an ongoing attack, so the testers kept going for some time. The gap wasn’t tooling; it was how alerts were triaged and prioritized. The client then changed its escalation rules and response procedures.

Pentest vs red team: which one do you need?

Pick by what you need to learn: which flaws in your systems can be exploited, or whether your team can stop an attack. Both sit within our penetration testing services.

• Choose a pentest if you need audit evidence, you’re changing a system, or you haven’t tested in a while.
• Choose a red team if pentest findings get fixed and you want to test your response.
• If you’re an EU financial entity, TLPT authorities assess which entities are required to run one. See threat-led penetration testing under DORA. We don’t provide threat intelligence and don’t hold TLPT accreditation.
