Penetration Testing
Identify and eliminate vulnerabilities in your external-facing infrastructure to prevent unauthorised access and breaches.
Discuss an engagementYour external infrastructure forms the frontline of your organisation's security perimeter, protecting critical assets from unauthorised access. While penetration testing focuses on identifying vulnerabilities within targeted external systems, true perimeter resilience requires a broader, continuous approach.
SilentGrid's External Infrastructure Penetration Testing simulates real-world attack scenarios to assess the security of internet-facing systems, identifying misconfigurations, unpatched services, and potential entry points for adversaries.
For organisations seeking a more comprehensive evaluation of their attack surface, our Perimeter Assessment extends beyond traditional penetration testing, uncovering and cataloguing all internet-exposed assets across your environment.
We assess your external infrastructure the way real attackers would, identifying exploitable misconfigurations, outdated services, and exposed entry points. This ensures vulnerabilities are detected and validated under conditions that mirror actual threats.
While external penetration testing targets specific systems or environments, our Perimeter Assessment delivers a holistic analysis of your entire internet-facing footprint. This service identifies forgotten or misconfigured assets that could inadvertently expose your organisation to risk.
We combine deep manual testing with automated scans to uncover hidden vulnerabilities that traditional tools often miss. This means chained exploits, overlooked misconfigurations and complex security flaws are identified, with guidance to fix them.
SilentGrid leverages custom tooling and continuous research to stay ahead of emerging attack vectors targeting external environments. Our focus on innovation ensures clients benefit from cutting-edge assessments that evolve alongside adversary techniques.
SilentGrid's external penetration testing adheres to established frameworks such as OWASP, CIS Benchmarks, and NIST 800-53, ensuring assessments align with industry best practices and security standards.
Plan the year
A single external infrastructure test finds the misconfigurations and unpatched services exposed to the internet. Where new infrastructure goes online through the year, an annual program puts external testing on a twelve-month plan, agreed a quarter at a time, with retesting each quarter.

SilentGrid's consultants are hand-picked, and between them they have delivered penetration testing globally over decades. Their sector experience covers banking and financial services, insurance, government, critical infrastructure and healthcare, so an assessment is read against how the systems in question are actually run.
Consultants find 0-day vulnerabilities in commercial software and speak or teach at security conferences. That research produces the custom tooling used to reach the flaws automated scanning leaves behind, and it keeps the techniques current. Testing follows concepts set out in NIST, OWASP, PTES and OSSTMM.

External infrastructure penetration testing examines the internet-facing systems in an agreed scope the way an outside attacker would: enumerating exposed hosts, DNS records and cloud resources, finding misconfigurations and unpatched services, safely exploiting them to prove impact, and checking whether a compromised external system leads into the internal network. A perimeter assessment, by contrast, first discovers everything that is exposed.
Internet-facing systems within the agreed scope. Exposed systems, DNS records and cloud resources are enumerated, then tested for misconfigurations, unpatched services, open ports and forgotten systems that offer an entry point.
External penetration testing targets specific systems or environments. A perimeter assessment delivers a holistic analysis of your entire internet-facing footprint, uncovering and cataloguing assets, including forgotten or misconfigured ones you may not know about.
Yes. Findings are validated and safely exploited to demonstrate impact, which also rules out false positives before anything is reported.
Yes. Pathways from compromised external systems into internal environments are assessed, along with the risks from exposed credentials, misconfigurations and open services.
Assessments adhere to established frameworks including OWASP, the CIS Benchmarks and NIST 800-53, so they align with recognised industry practice.
Yes. Continuous external infrastructure assessments run in regular cycles, commonly every 6 or 12 months, retesting prior vulnerabilities, assessing newly deployed infrastructure and applying emerging attack techniques as they appear.
A comprehensive vulnerability report covering severity and impact, proof-of-concept demonstrations for critical findings, a prioritised remediation roadmap, an executive summary, and post-engagement consultation with retesting to confirm fixes.
