Enterprise Penetration Testing

Expose Weaknesses Before Attackers Do

Your network is under constant threat—do you know where the vulnerabilities are hiding?

Seiso’s Enterprise Penetration Testing simulates real-world cyberattacks to uncover security gaps before malicious actors can exploit them. Our risk-based, adversary-focused testing doesn’t just check compliance boxes—it identifies true exploitable weaknesses, providing you with actionable insights to strengthen your defenses.

How Confident Are You That Your Business Can Withstand a Cyber Attack?

Our Enterprise Penetration Test (EPT) service meets you where you are, but is typically best for clients who have dedicated information security personnel and already have a moderately developed security program. For those not yet at this level of maturity, consider a Security Assessment.

Seiso’s penetration tests include customizable attack perspectives, such as an opportunistic attacker or nation-sponsored hacker, and the option to add wireless networks or social engineering to the scope.

Seiso’s cybersecurity specialists execute a controlled, real-world attack simulation on your external environment. We follow the Penetration Testing Execution Standard (PTES)—an industry-leading framework—to identify, exploit, and assess vulnerabilities that could expose your critical systems and sensitive data.

Testing Approach

We follow a structured, adversarial approach honed by decades of experience and countless tests across several industries.

Intelligence Gathering – We perform advanced reconnaissance to uncover critical data about your organization’s digital footprint. The more we learn, the more precise and dangerous our attack can be—just like a real adversary.

Threat Modeling – We map out high-value targets across your network, pinpointing attack paths that a motivated adversary would take to breach your systems.

Vulnerability Analysis – We analyze your infrastructure, applications, and configurations to identify weak points that attackers could exploit, from misconfigurations to insecure design flaws.

Exploitation – We go beyond scanning. Using ethical hacking techniques, we actively breach your defenses, demonstrating how an attacker could move through your environment undetected.

Post-Exploitation – Once inside, we assess the impact. Can an attacker steal sensitive data, escalate privileges, or move laterally? We show you what’s really at stake.

Remediation & Re-Test – Fixing vulnerabilities is just as critical as finding them. Seiso provides a complimentary re-test within four weeks to verify remediation of Moderate and higher severity vulnerabilities.
