Are you looking for a freelance penetration tester or considering hiring a certified pentester for your team?

Penetration tests are essential for identifying real-world vulnerabilities before attackers do. But the key question isn’t “do I need a pentest?”, but rather: how realistic and up-to-date is the test you will receive?

ISGroup does not provide commodity resources. We offer turnkey penetration testing projects, conducted by in-house specialists using an attacker-centric approach: the same method used by offensive teams in the real world.

Team services and expertise

Core technical skills

Our team covers all major attack surfaces:

• External and internal penetration tests on IT infrastructure, on-premise and cloud
• Web application and API testing, OWASP Top 10 and beyond
• Mobile application pentesting on Android and iOS
• Wireless and IoT security assessment
• Social engineering and phishing simulations (upon request)
• Red Teaming and Purple Teaming, advanced persistent attack simulations (APT-like)
• Active Directory and domain control testing, lateral movement, privilege escalation

Certifications and recognition

Our penetration testers hold the most sought-after and internationally recognized offensive certifications:

• OSCP (Offensive Security Certified Professional)
• OSEP, OSWE, OSED and other Offensive Security certifications
• CREST Registered Tester (where required)
• eCPPT, eWPTX, eJPT
• Participation in Bug Bounties, CTFs, and real-world offensive activities for international clients

Technologies and methodologies

We use both industry-standard tools and custom tools developed in-house:

• Offensive suites: Burp Suite Pro, Cobalt Strike, Metasploit, Nmap, BloodHound
• Scripting and automation with Python, Bash, PowerShell
• Manual techniques and TTPs updated to the MITRE ATT&CK framework
• Advanced reporting with technical detail, executive summary, and remediation plan
• Real-world simulations with clear rules of engagement, full documentation, and post-test support

When do you really need a penetration tester?

Specific use cases

Penetration testing is not a checklist exercise. It is a fundamental requirement in scenarios such as:

• Resilience verification before launching a new digital service
• Real risk assessment, integrated with audits, vulnerability scans, or ISO 27001
• Regulatory compliance (DORA, NIS2, GDPR, ISO 27001, PCI-DSS)
• Post-remediation technical analysis: verifying the closure of reported vulnerabilities
• Requests from enterprise clients or public entities for certified tests
• Adoption of a continuous security cycle (DevSecOps, CI/CD security)

Structured project vs. commodity resource

Hiring a pentester might seem more convenient. But in reality:

Commodity resource	ISGroup project
Often a single resource	Complete team with specialized experts
Dependency on automatic tools	Manual techniques simulated by real attackers
No scalability	Structured and repeatable approach
Raw, hard-to-read results	Executive report + technical remediation plan
No post-test support	Debriefing, vulnerability explanation, patching support

With ISGroup, you are not buying a test: you are buying the realistic simulation of an attack, structured to produce actionable, documented, and measurable results.

How our project-based approach works

Initial assessment

• Preliminary call to define objectives, scoping, and attack surfaces
• Information gathering on architecture, assets, and applications
• Definition of methodology (Black Box, Grey Box, White Box)
• Signing of Rules of Engagement (ROE), including authorization

Customized delivery

• Initial scanning and information gathering
• Manual execution of exploits, escalation, movement, and persistence
• Evidence collection and customized offensive simulations
• No impact on operations: tests in secure windows or “safe” mode
• Drafting of a complete report: executive + technical + CVSS prioritization

Measurable results

• Prioritization of vulnerabilities by real impact
• Reports valid for compliance and audits
• Useful material for internal training and technical awareness
• Technical follow-up for result analysis and remediation support

Frequently Asked Questions

• Can a penetration test cause service interruptions?
• No. Tests are performed following security best practices. We always plan activities to avoid impacts on production.
• How often should I perform a pentest?
• At least once a year or after every significant release, as suggested by standards such as ISO 27001, OWASP, and DORA.
• Is it possible to test only a part of the infrastructure?
• Yes. We can focus the project on web applications, cloud, internal infrastructure, Wi-Fi networks, or Active Directory, depending on your needs.
• Can I use your reports for ISO, DORA, or GDPR audits?
• Absolutely. Our reports include technical details, CVSS assessments, and executive sections ideal for demonstrating due diligence activities.
• How much time is needed for a penetration test?
• It depends on the scope. On average, a targeted test lasts between 5 and 10 working days, but we can adapt to more complex requirements.
