Insider Threat Testing

Insider Threat Testing Services

The Threat That Already Has a Badge

Perimeter defenses are designed to keep outsiders out. Insider threat testing asks a different question: what happens when someone who is already inside decides to cause harm, or when a legitimate credential falls into the wrong hands?

We simulate realistic insider scenarios using actual access levels within your environment. Starting from a position of legitimate trust, we map how far an attacker can move, what data they can reach, and whether your detection and response capabilities would catch them before damage is done.

Privilege Abuse & Escalation

We test whether users can access data, systems, or administrative functions beyond their authorized role, and whether privilege escalation paths exist from standard accounts to sensitive resources.

Learn more about privilege escalation

Lateral Movement

Starting from a single compromised or authorized account, we map how far an attacker can move across systems, segments, and trust boundaries without triggering alerts.

Learn more about lateral movement

Data Access & Exfiltration

We identify what sensitive data an insider can reach and whether they can extract it, through email, cloud storage, USB, print, or network transfer, without being detected or blocked.

Detection & Response Gaps

We evaluate whether your SIEM, EDR, DLP, and SOC would detect insider activity in real time. If we move through your environment without triggering an alert, you need to know that before a real insider does.

Learn more about detection engineering

Policy Enforcement Validation

We test whether access control policies, separation of duties, and least-privilege configurations are enforced in practice, not just documented in policy. Gaps between policy and reality are where insider threats thrive.

Learn more about access controls

Credential Compromise Scenarios

We simulate what happens when a valid credential is stolen through phishing, credential stuffing, or a third-party breach. Starting from that credential, we test how far the blast radius extends across your environment.

Pass Your Next Audit With Confidence

Penetration Testing

Companies turn to pentesting when they need real answers, not assumptions.
Maybe a customer is asking for proof, a compliance requirement is coming up, or they simply want to know if they’re actually protected.

Suzu Labs safely tests your systems the way a real attacker would, so you can see where things could break before it becomes a real problem.

Meet requirements for frameworks like SOC 2, ISO 27001, HIPAA, and PCI DSS with real, defensible testing, not just automated scans.
Show clients, vendors, and stakeholders that your security has been tested by real experts, not just assumed to be secure.
Turn one-time testing into ongoing validation so your security keeps up with new threats, not just audit cycles.
What We Test: Web-App, Mobile App, API, External Network, Internal Network, WIFI, Cloud, IoT, Physical.

PHYSICAL LAYER DEFENSE

Hardware Hacking

This usually comes up when something is on the line. A new device launch, customer trust, or protecting intellectual property.

We evaluate the security of your hardware and embedded systems to ensure they can’t be easily exploited, cloned, or manipulated in the real world.

When you’re shipping devices or relying on connected technology, unseen risks can lead to real consequences. From customer trust issues to expensive fixes. We help you catch those issues before they impact your business.
What We Hack: SCADA, IoT, OT, Vehicles, Embedded Systems.

What is insider threat testing?

Insider threat testing simulates scenarios where someone with legitimate access to your environment, whether an employee, contractor, or a stolen credential, attempts to abuse that access. We test privilege escalation, unauthorized data access, lateral movement, and data exfiltration to determine what an insider could accomplish and whether your controls would detect it.

How is this different from a standard penetration test?

A standard network penetration test typically starts from a position of zero access and works to gain a foothold. Insider threat testing starts from a position of trust, with legitimate credentials and authorized access, and tests what happens from there. The attack paths are different, the controls being tested are different (monitoring, DLP, separation of duties vs. perimeter defenses), and the findings are more focused on detection and response gaps than on initial access.

What types of insider scenarios do you simulate?

We simulate multiple scenarios depending on your risk profile: a disgruntled employee with standard user access, a compromised privileged account (IT admin, developer, DBA), a contractor with third-party VPN access, or a credential stolen through phishing. During scoping, we define which scenarios are most relevant to your organization and your threat model.

Will you test whether our SIEM and SOC detect the activity?

Yes. Detection validation is a core component. We coordinate with your security operations team so they are either aware of the test (to measure response) or unaware (to measure detection). Either way, we document which actions triggered alerts, which were missed, and provide specific recommendations for closing detection gaps.

What do you need from us to get started?

We need user accounts at the access levels being tested (standard user, privileged user, contractor, etc.), access to the environment, and an understanding of your organizational structure and trust boundaries. If you want us to test detection capabilities, we need to coordinate with your SOC or managed security provider on whether the test is announced or unannounced.

How long does an insider threat test take?

Most engagements run one to three weeks depending on the number of scenarios being tested, the size of the environment, and whether detection validation is included. We provide a clear timeline during scoping, and if we discover a critical finding that poses an imminent threat, we escalate it to your team immediately.

What happens after the report?

The report is the beginning, not the end. You get a live debrief with the operators who ran the engagement, walking through every finding, its real-world impact, and specific remediation steps. If your team needs hands-on help remediating, whether that's tightening access controls, tuning SIEM rules, or reconfiguring DLP policies, we can work alongside your engineers. Once fixes are in place, we conduct retesting to verify they're effective.

Insider Threat Testing vs. Network Penetration Testing

	Insider Threat Testing	Network Penetration Testing
Starting Position	Begins with legitimate credentials and authorized access inside the environment	Begins with no access (external) or a simulated foothold with minimal privileges (internal)
Scope	Privilege abuse, data access, lateral movement from trusted accounts, detection and response validation	Infrastructure exploitation, credential attacks, segmentation bypass, Active Directory compromise
What's Being Tested	Monitoring, DLP, access controls, separation of duties, SOC detection capabilities	Firewalls, network segmentation, authentication protocols, endpoint protections
Common Findings	Excessive permissions, unmonitored data access, lack of alerting on privilege abuse, policy enforcement gaps	Weak credentials, unpatched services, AD misconfigurations, segmentation failures
Impact if Undetected	Data theft, fraud, intellectual property loss, regulatory violations, reputational damage	Domain compromise, ransomware deployment, mass data exfiltration
Ideal For	Organizations concerned about credential compromise, privilege abuse, regulatory compliance (HIPAA, PCI, CMMC), or SOC effectiveness	Organizations validating perimeter defenses, network architecture, and infrastructure resilience
