Penetration Testing Services
Identify and mitigate security risks before they become costly breaches with CREST-certified penetration testing.
Why Penetration Testing Matters
Cyber threats are constantly evolving, with thousands of new vulnerabilities discovered every year. While businesses invest in firewalls, antivirus software and other security controls, attackers only need to exploit a single weakness to gain access to your systems.
A penetration test evaluates your organisation’s security by simulating real-world cyber attacks against your internet-facing and internal network infrastructure. Unlike an automated vulnerability scan, penetration testing validates whether identified vulnerabilities can actually be exploited, helping you understand the real risk to your business.
By identifying security weaknesses before attackers do, penetration testing enables you to prioritise remediation, strengthen your cybersecurity posture and reduce the risk of data breaches, ransomware attacks and costly business disruption. Our CREST-certified penetration testing service gives you confidence that your assessment follows recognised industry standards and best practice.

How a Penetration Test with ABS Works
Our CREST-certified penetration testing process follows a structured, five-stage methodology that mirrors the techniques used by real-world attackers. From defining the scope to validating remediation, every stage is designed to identify exploitable weaknesses, minimise disruption and deliver practical recommendations for improving your security.
- 01
Scope & Planning
We work with you to define the external and internal network infrastructure to be tested, agree the rules of engagement and establish clear objectives for the assessment.
- 02
Discovery & Reconnaissance
Our security consultants map your environment to identify internet-facing assets, services, IP-addressable devices and potential attack paths that could be targeted by a malicious actor.
- 03
Active Penetration Testing
Using a combination of manual penetration testing techniques and advanced security tools, our CREST-certified penetration testing service safely assesses your environment for exploitable vulnerabilities, misconfigurations, weak authentication controls and privilege escalation opportunities.
- 04
Reporting & Recommendations
You'll receive a comprehensive report detailing every validated finding, including risk ratings, technical evidence, business impact and prioritised remediation recommendations, supported by a plain-English executive summary.
- 05
Remediation & Retesting
After vulnerabilities have been addressed, we retest your environment to verify that remediation has been successful and confirm your security controls are working as intended.
Don’t Wait for a Cyber Attack
A security vulnerability doesn’t become a business risk until it’s exploited. Our CREST-certified penetration testing services identify exploitable weaknesses before attackers do, helping you strengthen your cybersecurity, reduce business risk, support compliance and protect your critical systems, data and reputation.
Penetration Test
A penetration test goes beyond automated vulnerability scanning by simulating the techniques used by real-world attackers. Using a combination of manual and automated testing, our security consultants attempt to exploit vulnerabilities within your external and internal network infrastructure to determine the true level of risk to your organisation. Our assessments are delivered through a CREST-certified penetration testing service, providing assurance that testing is performed using recognised methodologies and industry best practice.
Penetration testing uncovers security weaknesses such as weak passwords, exposed sensitive data, insecure configurations, privilege escalation opportunities, network share permission issues and multi-stage attack paths that automated tools often fail to identify.
The result is a realistic assessment of your security posture, supported by prioritised remediation recommendations that help you reduce cyber risk, strengthen your security controls and improve your resilience against cyber attacks.
Vulnerability Test
A vulnerability test (or vulnerability assessment) identifies known security vulnerabilities across your networks, systems and applications. It uses automated tools to detect missing security patches, outdated software, insecure configurations, default credentials and other common weaknesses that could be exploited.
Vulnerability testing provides broad visibility across your IT environment and is an effective way to identify and prioritise known risks. However, it does not attempt to exploit vulnerabilities or demonstrate how an attacker could combine multiple weaknesses to compromise your systems.
For the strongest cybersecurity strategy, vulnerability testing and penetration testing work together. Regular vulnerability assessments help you identify known issues at scale, while penetration testing validates your security by simulating real-world cyber attacks and uncovering the risks automated scanning cannot detect.

Penetration Testing FAQs
Find answers to common questions about penetration testing, vulnerability assessments, reporting, remediation and compliance.
Penetration testing is a controlled cybersecurity assessment that simulates the techniques used by real-world attackers to identify exploitable security vulnerabilities. Unlike automated vulnerability scans, a penetration test attempts to validate whether weaknesses can actually be exploited, helping organisations understand their true level of cyber risk.
A vulnerability assessment identifies known security weaknesses using automated tools, such as missing patches, outdated software and configuration issues. A penetration test goes further by attempting to exploit those vulnerabilities to determine the potential impact of a real cyber attack. Both services are valuable, but penetration testing provides a more realistic assessment of your security posture.
Most organisations should perform penetration testing at least annually. Testing is also recommended after significant infrastructure changes, cloud migrations, new application deployments, mergers or acquisitions, or whenever required for compliance with standards such as Cyber Essentials Plus and ISO 27001.
Penetration testing can be performed against internal and external networks, web applications, cloud environments, Microsoft 365, wireless networks, Active Directory, remote access solutions, APIs and other critical business systems. Testing is tailored to your organisation’s environment and security objectives.
Professional penetration testing is carefully planned to minimise disruption. Before testing begins, the scope, methodology and schedule are agreed to ensure business-critical systems remain protected. Any higher-risk testing activities are discussed and approved in advance.
Following the assessment, you’ll receive a detailed penetration testing report that includes an executive summary, technical findings, risk ratings and prioritised remediation recommendations. Where required, ABS can support your team with remediation guidance and perform a retest to verify that vulnerabilities have been successfully resolved.
Yes. Penetration testing supports many cyber security and compliance frameworks by demonstrating that your organisation regularly assesses and manages security risks.
