Network Penetration Testing
Your network is the terrain an attacker actually fights on. We test it the way an intruder would — across your external perimeter and your internal estate — going far beyond port scanning to prove how a single foothold becomes full compromise.
Veteran researchers. CERT-In empaneled. Manual exploitation, not just a scan report.
Beyond the scan, into the network
A network assessment that stops at open ports and a list of CVEs tells you where the doors are — not whether anyone can walk through them.
Real intrusions rarely turn on a single dramatic exploit. They begin with a modest foothold, then escalate: harvested credentials, a misconfigured service, a trust relationship abused, a path traced quietly from one host to the next until an attacker holds the domain. The risk that matters is not the vulnerability in isolation. It is the chain.
We test that chain. Across your external perimeter and your internal corporate network — and, where Wi-Fi is in scope, your wireless environment — our researchers combine automated discovery for breadth with manual, hands-on exploitation for the depth and judgment a scanner cannot reach. We confirm what is genuinely exploitable, demonstrate how far it reaches, and measure the business impact — then report it with the evidence and the remediation your team needs.
"A scanner finds the open door. An attacker walks through it, then finds the next one. We test the whole walk."
External and internal
Different vantage points reveal different risks. We assess both your perimeter and your internal estate — together they describe how exposed you really are — and can extend the engagement to your wireless edge where Wi-Fi is in scope.
The view from the internet
We assess your internet-facing infrastructure exactly as an anonymous, unauthenticated attacker would encounter it — enumerating exposed hosts, services and entry points, then attempting to gain an initial foothold from the outside. This is the truest test of your perimeter and the gateway most real intrusions pass through.
What happens once they're inside
Starting from a position inside your network — a compromised workstation, a contractor's access, a single set of stolen credentials — we model the assumed-breach scenario that defines modern attacks. From there we pursue privilege escalation, credential access, lateral movement and the Active Directory paths (Kerberoasting, relay attacks, trust abuse) that lead to domain dominance.
Wireless
Where Wi-Fi is part of the in-scope environment, we can extend the engagement to your wireless edge — testing for weak or crackable WPA2/WPA3 pre-shared keys, captured handshakes and PMKID, rogue access points and evil-twin attacks against enterprise wireless, and the segmentation failures that let a wireless or guest client reach the corporate network it should never touch.
What an attacker is really after
Every finding we report ladders up to a real adversarial goal. We test for the outcomes an intruder pursues, not just the vulnerabilities in isolation.
Gaining a foothold
Turning an exposed service or weak credential into the first authenticated step inside.
Escalating privileges
Moving from a low-privilege account to local admin, then toward domain control.
Harvesting credentials
Extracting passwords, hashes and Kerberos tickets to unlock the next host.
Moving laterally
Pivoting host to host and segment to segment, following trust the network already grants.
Reaching critical assets
Reaching the data stores, domain controllers and management planes that run the business.
Maintaining access
Establishing the persistence and evasion a real intruder would use to stay unnoticed.
A disciplined, attacker-led methodology
We follow a structured methodology aligned with recognized standards — NIST SP 800-115 and the Penetration Testing Execution Standard (PTES) — so coverage is repeatable and defensible, while the exploitation itself stays creative and adversarial. Within the engagement, the offensive actions we take are mapped to the MITRE ATT&CK framework, so every step is named in the same language your defenders use. Each phase opens into the specific attacker tactics beneath it.
Tools find the obvious. People find the dangerous.
Both have a role. We use each for what it does best — and we never let a scan stand in for an assessment.
Breadth, at speed
Automated tooling rapidly discovers in-scope hosts, sweeps for open ports and services, and flags known, signature-based weaknesses across a wide surface. We treat its output as a starting point — every result is triaged by an analyst and false positives are eliminated before anything reaches your report. Suited to establishing baseline exposure across non-critical assets at scale.
Depth, with judgment
The findings that decide a breach — chained exploits, privilege escalation, credential reuse, trust abuse and the Active Directory attack paths that turn one host into a domain — require a researcher who understands how an attacker reasons. Our analysts examine each open port and service by hand, exploit and chain real weaknesses, and pursue the lateral paths no automated tool is built to follow.
Choose the depth of visibility
We tailor the engagement to how much we know going in. More context means deeper coverage in the same window.
We test with no internal knowledge of the target — exactly as an outside attacker would encounter it. A black-box engagement determines what is exploitable from beyond the network, with no credentials or documentation provided. Best for validating your true external exposure.
We test with partial knowledge: network design and architecture documentation, and a measure of internal access to in-scope assets. This is the most common and cost-effective model for internal engagements — it lets us reach deeper, role-specific and post-authentication weaknesses far more efficiently.
Full-knowledge reviews of firewall rules, device configurations and network architecture are delivered under our Network Configuration & Firewall Rules Review service.
What we test against
Across an engagement we systematically probe the control areas that determine whether a foothold stays contained or becomes a compromise:
01 Authentication How identities are verified across the estate, including the protocols (such as Kerberos) that underpin enterprise authentication and the attacks that target them.
02 Authorization Whether the right entities are granted the right access, and how authentication data is protected as it moves between systems.
03 Data at Rest Protection of data stored on system drives, external media, storage-area networks (SANs) and backups.
04 Data in Transit Protection of data moving across wired, wireless, internal and public networks against interception and downgrade.
05 User Input Handling Injection and input-handling flaws exposed on network services — SQL injection, OS command injection, cross-site scripting, insecure file upload, HTTP response splitting and related classes.
06 Updates & Upgrades Firmware versions, operating-system patch levels and hotfixes across in-scope assets.
07 Logging & Monitoring Whether activity is logged and observable enough to detect an intrusion — and what those logs may inadvertently expose.
08 Misconfiguration Default, weak or unsafe configurations that disclose internal or sensitive information, or that hand an attacker an unintended advantage.
09 Password Management Credential strength, storage and management across the network, and resistance to spraying, brute force and offline cracking.

A clear path from kickoff to remediation — built to give your team findings they can act on immediately, in the language their defenders already use.
What we can test
If it's reachable on your network, it's in scope. The same attacker mindset extends across the whole estate.
What you receive
Every engagement ends in a report your team can act on — written for both the engineers who will fix the issues and the leaders who must understand the risk.

Frequently asked questions
How is this different from a vulnerability scan?
A scan produces a list of potential issues from known signatures. A penetration test confirms what is actually exploitable, chains weaknesses the way an attacker would — foothold to privilege escalation to lateral movement — and measures how far an intrusion really reaches. We use scanning as one input, never as the assessment itself.
Should we test externally, internally, or both?
External testing reflects an anonymous internet attacker and validates your perimeter. Internal testing assumes that perimeter is eventually crossed — by phishing, a stolen credential or an insider — and measures the damage from there. Most organizations need both, because the two answer different questions. Wireless is assessed where Wi-Fi is part of the in-scope environment.
What is "assumed breach," and why test that way?
Modern attackers almost always get inside eventually. Assumed breach starts the internal engagement from a realistic foothold and asks the question that matters most: once they're in, how far can they get? It is the fastest route to the privilege-escalation and Active Directory findings that decide a real incident.
Will testing disrupt our production network?
We scope and pace engagements to avoid operational impact, coordinate windows with your team, and treat any potentially intrusive testing — including wireless deauthentication or denial-of-service demonstrations — with explicit, written agreement.
How often should we test?
At minimum annually, and after any significant change to your network, infrastructure or Active Directory — as well as when compliance requires it. Frequently changing environments benefit from a recurring cadence.
Do you retest after we fix the issues?
Yes. Remediation retesting is included so you can confirm each finding is genuinely resolved.
