Build a Defensible Security Foundation

You need more than a checklist to know your infrastructure is secure. Packetlabs validates foundational controls across your perimeter, identity systems, cloud environments, and internal infrastructure to showcase how they hold up against real-world attack techniques. Your team gets clear evidence, remediation guidance, and retesting support to strengthen compliance, prioritize fixes, and show stakeholders that risk is being reduced.

What We Test Across Your Infrastructure

You don't need everything tested. You need the attack paths that actually put systems and data at risk. Our infrastructure penetration testing focuses on the routes adversaries use most.

Close the Gaps Attackers See From the Outside

We test your internet-facing perimeter, including firewalls, VPNs, remote access portals, exposed services and email gateways, to find weaknesses an external attacker could use to get in. Every finding is manually validated, so you can fix confirmed risks instead of chasing scanner noise.

See How Far an Attacker Could Move Inside Your Network

Starting from an assumed foothold, our testers use misconfigurations, weak protocols, unpatched systems and exposed credentials to move laterally across your internal network. You get a clear picture of how one compromised device could become a business-wide breach.

Test the Identity Layer That Holds Your Network Together

We assess Active Directory and Entra ID for privilege escalation paths, Kerberos and NTLM weaknesses, excessive permissions and risky trust relationships. Each attack chain comes with prioritized fixes so your team can cut off the routes to domain admin.

Validate Segmentation Across On-Premises, Cloud, and Hybrid Environments

We check whether network segmentation, firewall rules and cloud connectivity contain an attacker or let them reach critical systems and sensitive data. Testing covers wireless, VLAN and hybrid cloud boundaries to show how well your environment holds up under real attack conditions.

What Our Clients Say

Infrastructure Pen Testing: Key Outcomes

Your team leaves with proof: what's reachable, what's chainable, and what to fix first to reduce real breach risk.

Stop Local-to-Cloud Breakouts

Identify how a compromised endpoint can pivot into backend systems and close the path.

Eliminate Exposed Secrets

Find and remove hardcoded credentials, tokens, and unsafe local storage patterns.

Harden Critical Systems

Prioritize fixes that actually block exploitation beyond patch lists and generic checkups.

Catch New Exposure Early

Spot changes in external attack surface and validate controls after meaningful change.

Get Audit-Ready Evidence

Document controls, testing outcomes, and remediation verification for stakeholders.

Enable Your Team

Work side-by-side with your engineers and security team to transfer attack knowledge.

Infrastructure Penetration Testing vs. Red Teaming

Infrastructure testing should prove security is working not generate noise. Here's what's different when testing is led by real attack paths.

Infrastructure Penetration TestingAdversary Simulation (Red Team Testing)

Scope

Focuses on networks, servers, firewalls, cloud infrastructure, and internal systems

Simulates full-scope real-world attacks across people, processes, and technology

Attack Surface

Evaluates exposed services, VPNs, Active Directory, cloud configs, and internal segmentation

Tests external perimeter, internal systems, identity controls, detection capabilities, and response readiness

Primary Objective

Identify vulnerabilities that allow unauthorized access or lateral movement

Measure how far a real attacker could go before being detected and stopped

Common Weaknesses Identified

Open ports, misconfigurations, weak segmentation, outdated services, insecure remote access

Gaps in detection, alert fatigue, privilege escalation paths, weak response coordination

Testing Approach

Targeted testing of infrastructure components to uncover exploitable weaknesses

Goal-driven attack simulation designed to achieve defined objectives (e.g., domain admin, data exfiltration)

Authentication & Access Control

Tests Active Directory security, privileged accounts, IAM roles, and segmentation controls

Attempts credential theft, privilege escalation, phishing, and identity abuse

Detection & Response Validation

Limited focus on SOC performance unless scoped

Directly evaluates SOC detection, alerting, and incident response effectiveness

Impact if Compromised

Network foothold, ransomware risk, internal system exposure

Full attack chain simulation demonstrating business-level impact

Ideal For

Organizations validating infrastructure hardening and configuration security

Mature organizations wanting to test real-world resilience and detection capability

Infrastructure Penetration Testing FAQs

Clear scope. Realistic attack paths. Evidence you can act on. Our infrastructure penetration tests are tailored to your environment on a prem, cloud, or hybrid, so results map to how you operate, not a generic template.

What's included in an infrastructure penetration test?

We test external exposure and internal attack paths across networks, servers, and identity. That can include VPN/remote access, segmentation, AD pathways, privilege escalation, and hybrid trust relationships. Scope is defined around what would meaningfully reduce risk in your environment.

Why Security Leaders Choose Packetlabs

Since 2011, Packetlabs has been helping organizations find real attack paths, prioritize remediation, and prove measurable risk reduction through human-led penetration testing.

95% Manual Testing Our pentest services combine expert manual testing with targeted automation to show what attackers could reach across infrastructure, identity, and cloud environments.

OSCP-Minimum Testers Every tester holds OSCP at a minimum, with advanced certifications across the team, including OSEP, OSWE, GXPN, GWAPT, GMOB, GSNA, GCIH, CISA, and CISSP.

CREST-Accredited and SOC 2 Type II Attested Work with a trusted pentest company in Canada built for security, compliance, and vendor-risk requirements.

Retesting Included Retesting is included so your team can confirm fixes and show measurable risk reduction.
