Penetration Testing & Vulnerability Scanning

ACSG’s Penetration Testing and Vulnerability Scanning services are designed to identify security gaps before attackers can exploit them. We test your systems and procedures to determine where there are gaps in your security plan, then guide you in addressing them. Whether it’s a misconfigured firewall, an outdated application, or a weak access control policy, our thorough assessments help you prioritize and remediate issues before they become critical.

Our comprehensive approach includes both internal and external evaluations. We assess internal and external devices, web applications, and operational technology for vulnerabilities and exposures. This includes simulated attacks to mimic real-world threat actors, revealing how an intruder might infiltrate your network or escalate access once inside. Our tests go beyond surface-level scans to identify hidden risks in your infrastructure, user access practices, and system integrations.

Vulnerability scanning provides regular, automated detection of known security issues across your environment. Combined with manual penetration testing, it delivers a layered understanding of your risk posture. Our experts tailor testing strategies to your environment, ensuring relevance to your business operations, compliance requirements, and industry best practices.

After testing, we deliver a clear, actionable report that highlights findings, their risk levels, and prioritized recommendations. We don’t stop at identification—we work closely with your team to guide remediation efforts, improve your security posture, and strengthen your organization’s overall resilience against cyber threats.
