Top 5 Red Teaming Companies in 2025

The modern cybersecurity landscape is very different from the landscape from 20, 10, or even 5 years ago. Attacks that plagued organizations used to be relatively simple and isolated, but today, it is sophisticated and targeted campaigns that give cybersecurity teams sleepless nights.

In this challenging landscape, it’s not enough to only implement cybersecurity tools. It’s equally important to test the effectiveness of those tools by emulating the tactics, techniques and procedures (TTPs) of real attackers, and understanding how they could cause real damage to your organization, which is why red teaming is so important today.

What is Red Teaming?

Red teaming is a cybersecurity exercise in which teams of ethical hackers simulate nondestructive cyberattacks against a full enterprise ecosystem, which includes people, processes, and technology, to:

• Uncover realistic attack paths that may allow real-world attackers to access critical systems
• Stress-test existing defenses to identify gaps in threat detection and incident response
• Demonstrate the possible business impact of a real attack
• Provide actionable recommendations to improve cyber-resilience

Red teamers emulate the TTPs and tools of real adversaries to deliberately attack the organization. Their goal: to identify security vulnerabilities and highlight how real attackers may exploit those vulnerabilities to harm the organization.

Top 5 Red Team Service Providers in 2025

1. BreachLock

Expert-led RTaaS and GenAI-powered autonomous red teaming to scale protection against evolving threats

BreachLock delivers Red Teaming as a Service (RTaaS), blending human expertise with automation to make red teaming faster, more efficient, and more actionable. Traditional red team exercises are often slow, costly, and hard to repeat at scale—but BreachLock’s approach changes that. With RTaaS, enterprises can continuously validate defenses against the latest attacker tactics, techniques, and procedures (TTPs) while reducing the cost and complexity of maintaining a full in-house red team.

For organizations that want even more control, BreachLock also offers Adversarial Exposure Validation (AEV)—a generative AI-powered autonomous red teaming tool. AEV allows internal security teams to launch unlimited, multi-step, threat-intelligence-led attack scenarios on demand. Teams can adjust parameters like attack intensity and scope, then receive evidence-backed visualizations of attack paths showing exactly where defenses succeed or fail. This empowers teams to prioritize and remediate the exposures that matter most—before attackers can exploit them.

By combining managed RTaaS with the option for self-directed AEV, BreachLock gives enterprises unmatched flexibility: continuous expert-led testing when needed, plus the ability to autonomously extend coverage at scale. This dual approach makes BreachLock an ideal partner for organizations that need scalable, cost-effective, and outcome-driven red teaming without compromising on realism or depth.

2. CyberArk

CyberArk’s red team specializes in adversary simulations targeted at the exploitation of organizations’ cloud and hybrid environments, DevOps pipelines, and processes. Just like real attackers, the red teamers use different methods to uncover vulnerabilities, test security procedures, and recommend feasible improvements.

Key features:

• Depending on their unique security concerns, clients can ask CyberArk to test against known or unknown threats
• Quantify the firm’s security posture at a particular point in time
• Detailed post-engagement report that enumerates discovered vulnerabilities, plus the business impact of those findings

3. Redscan (Kroll)

Redscan’s red teaming service combines offensive security testing experts with intelligence-led testing to assess how organizations detect and respond to threats. The experts test physical and virtual cybersecurity controls to assess cyber-preparedness, and use advanced techniques that reflect the approach of real-world attackers.

Key features:

• Multi-blended attack methods provide in-depth testing and uncover hidden vulnerabilities
• Detailed report with actionable insights to help accelerate risk remediation
• Post-operation support to effectively address identified vulnerabilities

4. Security Scorecard

Security Scorecard’s red teaming exercises enable organizations to evaluate their defensive capabilities and boost their preparedness to deal with real cyberattacks. Their red team runs sophisticated simulations to uncover vulnerabilities and provide comprehensive analyses of cyber risks. They also customize red team scenarios to fit a client’s unique business environment and threat landscape.

Key features:

• Proactive and targeted assessments aimed at enhancing clients’ cybersecurity practices
• Realistic simulations provide deep, contextual insights into the client’s response capabilities
• Detailed, business-friendly report with practical recommendations to strengthen the security posture

5. Mindgard

Mindgard’s red teaming solution supports continuous testing for AI systems. The solution is designed to identify AI-specific risks that can only be detected during runtime and that traditional security tools often miss. Mindgard red teaming is suitable for organizations looking for comprehensive threat protection and security assurance with continuous testing across the AI SDLC.

Key features:

• Automated AI red teaming that works with all AI models and guardrails
• Integrates into existing CI/CD automations, reporting, and SIEM systems
• Provides extensive coverage for image, audio, and multi-modal AI systems

Conclusion

Organizations looking to improve their security preparedness and incident readiness in today’s threat landscape significantly benefit from regularly conducting red teaming assessments to:

• Understand how a real attacker would act in their environments
• Test how well their detection and response procedures work under stress
• Prioritize fixes based on risk context and real business impact
• Harden defenses, and reduce incident dwell time and recovery time

Those benefits aside, traditional red teaming is a labor-intensive, human-dependent process that cannot keep up with today’s fast-expanding cyberthreat environment. It also doesn’t typically integrate findings with the in-house team’s tech stack, and one-off engagements don’t support continuous testing and may therefore miss regressions or drifts in defenses over time.

RTaaS and AEV, when leveraged together, can mitigate these risks efficiently and scalably, even in vast enterprise ecosystems. Learn how BreachLock RTaaS and AEV can help to safeguard your business-critical systems and data. Click here to schedule a free discovery call with our experts.
