- Establish the scope of the environment under test.
- Choose the right testing methods and approach.
- Plan communication and coordination processes.
Execution Phase (During the Test)
- Conduct fieldwork and identify services.
- Build or use custom scanning and attack tools if needed.
- Find security flaws while filtering out false positives.
- Attempt to exploit vulnerabilities to gain access.
- Use compromised systems to mimic real-world attacks.
Reporting & Remediation Phase (After the Test)
- Analyze all test results and recommend prioritized fixes.
- Help with remediation such as isolating network issues, fine-tuning configurations, or fixing insecure code.
- Conduct follow-up testing to ensure all vulnerabilities have been fixed.
Comparing Automated and Manual Penetration Testing: Which Is Right for You?
-
Advantages of Automated Penetration Testing
- Requires minimal technical expertise to operate tools.
- Identifies a broad range of well-known security vulnerabilities.
- Faster execution compared to manual methods.
- More cost-effective than hiring expert testers.
- Can be conducted regularly for continuous security monitoring.
-
Advantages of Manual Penetration Testing
- Simulates real-world attack strategies and hacker behavior.
- Delivers highly accurate results with no false positives.
- Customizable to meet specific security objectives and systems.
- Provides in-depth reports with actionable remediation steps.
-
Disadvantages of Automated Penetration Testing
- Lacks the depth to uncover complex or logic-based vulnerabilities.
- May overlook critical business-specific risks.
- Often falls short of compliance standards (e.g., PCI DSS).
-
Disadvantages of Manual Penetration Testing
- Requires experienced professionals with deep technical skills.
- Typically more time-intensive than automated scans.
- Involves higher upfront investment than tool-based testing.

FAQs about Penetration Testing Services
Penetration testing is a simulated cyberattack conducted by ethical hackers to identify and exploit vulnerabilities in your system. It helps uncover security weaknesses before malicious hackers can exploit them, ensuring stronger defense and compliance with security standards.
Penetration testing is essential for any organization that handles sensitive data, operates critical infrastructure, or wants to comply with regulatory standards such as HIPAA, CCPA, NAIC Standards, AML Standards, and ISO 27001. It’s especially vital for companies with web applications, remote access solutions, or a growing digital footprint.
We follow strict security protocols validated by ISO 27001 certification and always sign non-disclosure agreements (NDAs). All testing is conducted in a controlled, ethical, and secure manner to protect your data.
The duration varies by project scope and complexity. Typically, the testing phase lasts 3–10 days. The full process, from planning to final reporting, usually spans 2–4 weeks.
Yes. Our experienced developers and security engineers can remediate any vulnerabilities identified during testing. We aim to be your one-stop solution for security improvement.
After a 2-week window for fixes, we conduct a second round of testing to verify that all previously found vulnerabilities have been resolved. If more time is needed for remediation, we accommodate accordingly and retest without compromising your security improvement timeline.
Penetration testing helps reduce risks from threats such as ransomware, phishing attacks, insider threats, stolen devices, remote work vulnerabilities, and compliance breaches.
We utilize industry-standard tools such as Burp Suite, Metasploit, Nmap, OWASP ZAP, Nessus, Nikto, and more. These tools help with vulnerability assessment, network analysis, and secure code review.
