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 show 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.

Installer & Update Security

Validate signing, packaging, and update channels so attackers can't swap binaries or hijack distribution.

Read the intro guide to Infra Pentesting

Local Data & Secrets

Find exposed keys, tokens, PII, and unsafe caching in files, registries, keychains, and memory dumps.

Learn how to secure PII

Identity & AD Pathways

Test how quickly a compromise becomes domain-level access through misconfigurations, weak controls, or privilege sprawl.

Read about pentesting pricing

Server & Endpoint Weaknesses

Validate hardening, patching, and local escalation paths that attackers use to gain persistence.

Learn about best patch management practices

Hybrid & Cloud Trust

Assess cloud connectivity, IAM, and trust relationships that expand blast radius in hybrid environments.

Assumed Breach Simulation

Start from a realistic foothold and measure how far an attacker can move fast.

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 Testing	Adversary 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.

Do you test both internal and external networks?

Will you retest fixes?

How do you prioritize findings?

Can you align results to compliance requirements?

Can I just use an AI tool for infrastructure pentesting?

AI tools can help with parts of security testing, but they cannot replace a real infrastructure penetration test. Your team still needs experienced testers to validate exploitability, safely test attack paths, connect weaknesses across identity, cloud, and internal systems, and prioritize what actually reduces risk. Packetlabs uses AI where it adds value, but every engagement is led by human pentesters who verify findings and focus on real-world impact.

Why Security Leaders Choose Packetlabs

Since 2011, Packetlabs has delivered 1,500+ engagements helping organizations find real attack paths, prioritize remediation, and prove measurable risk reduction through human-led infrastructure 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.
