Penetration Testing
See where an attacker could get in—and how far they could go
ProCircular’s ethical hackers test for real access paths, then show what attackers could expose and which fixes should move first.
From access path to priority fix
A strong pen test helps your team understand how adversaries could gain access, where they could move, what they may be after, and which fixes to prioritize.
How adversaries gain access
Identify viable access paths across internet-facing systems, applications, credentials, exposed services, or social engineering scenarios where scoped.
Where access could lead
See how an initial foothold could expand through privilege escalation, lateral movement, weak configurations, or internal trust relationships.
What attackers may be after
Understand whether a path could lead to sensitive data, critical systems, backups, applications, file shares, or infrastructure that supports the business.
What your team should fix first
Prioritize remediation based on exploitability, business impact, attack path, and the risk each finding creates.
Penetration testing built around real attack paths
Each engagement is scoped around the attack surfaces that matter most, then tested through reconnaissance, discovery, manual exploitation, and post-exploitation validation.
External testing
Our team assesses internet-facing systems from an attacker’s perspective, using reconnaissance, credential attacks, vulnerability exploitation, and foothold testing to show how someone could gain access.
Internal assumed-breach testing
We simulate what could happen after access is gained, including lateral movement, privilege escalation, password and access-control testing, file-share access, and paths to critical systems.
Application and API testing
Our testers evaluate web applications, APIs, authentication, authorization, business logic, and chained vulnerabilities that can affect sensitive data or application integrity.
Social engineering where scoped
When included, phishing, vishing, or other approved scenarios help test how human-facing attack paths could support broader access.
Test what happens after access is gained
Where scoped, ProCircular tests how an initial foothold could expand across users, systems, credentials, permissions, and data.
Escalation paths
Test whether limited access could expand through weak permissions, misconfigurations, vulnerable systems, or privilege escalation paths.
Lateral movement
Assess how access could move across systems, users, file shares, trust relationships, Active Directory, and internal services.
Credentials & permissions
Identify exposed passwords, tokens, weak access controls, over-permissioned accounts, and identity paths that could help an adversary move further.
Sensitive systems & data
Demonstrate whether an attack path could reach sensitive data, business applications, backups, critical systems, or infrastructure your team needs to protect.
A report your team can act on
Our penetration test report gives your technical teams the evidence and remediation steps to fix what we found, along with a clear summary for the people making risk, budget, and priority decisions.
Executive summary
A clear explanation of the most important risks, business implications, and remediation priorities.
Technical findings
Detailed findings with severity, affected systems, exploitation evidence, screenshots, and supporting technical context.
Remediation roadmap
Recommendations organized around risk, priority, and the steps your team can take to address each finding.
Attack-path narrative
A practical view of how access could develop across systems, credentials, applications, permissions, or infrastructure.
Engineer readout
A direct discussion with ProCircular engineers so your team can ask questions, understand the findings, and plan remediation.
Testing led by award-winning engineers
Each engagement is led by a U.S.-based ProCircular specialist, backed by teams who test, investigate, and monitor real attack activity across client environments.
One lead engineer, backed by a team
Each engagement has a clear technical lead, supported by ProCircular specialists who can bring additional perspective when the environment or findings call for it.
Award-winning technical discipline
Our team includes engineers who compete and win in national cybersecurity competitions, including capture-the-flag and threat-hunting events. That same discipline shapes how we test, validate, and explain what we find.
Real-world attack knowledge
Our methods are shaped by the incidents, attacker behaviors, and exploitation paths our teams see across client environments.
A process your team can follow
We communicate throughout the engagement, explain what we found, and make the results usable for technical remediation, risk discussion, and future planning.
Clear next steps
The results can support remediation, retesting, MXDR monitoring, a broader cybersecurity risk assessment, or ongoing advisory support through CAP.
Start with the pen test that fits your environment
Whether you need an external pen test, internal assumed-breach testing, application/API testing, or a scoped combination, ProCircular can help you choose the right starting point.
