Offensive Security.
Defensive Confidence.

Penetration testing (also called a pentest or ethical hacking) is a controlled, authorized simulation of a real-world cyberattack against your systems. A penetration testing company like Jelliphish employs security experts who use the same tactics, techniques, and procedures as malicious hackers — but with your permission and in a safe, scoped manner.

Your business needs penetration testing services because automated vulnerability scanners only catch known issues. A skilled penetration tester chains together low-risk findings to demonstrate real business impact — such as accessing customer data, moving laterally through your network, or escalating privileges to domain admin. Regular pentests help you meet compliance requirements, validate your security controls, and fix exploitable weaknesses before adversaries find them.

A vulnerability assessment is a broad, largely automated scan that identifies known security weaknesses across your environment and ranks them by severity. It tells you what might be wrong. A penetration test goes further: our ethical hackers actively attempt to exploit those vulnerabilities to determine real-world impact, chain findings together, and demonstrate how an attacker could compromise your systems.

Think of a vulnerability assessment as a security audit checklist, while a penetration test is a full adversary simulation. Many organizations benefit from both — regular vulnerability assessments for continuous monitoring, and periodic penetration tests for deeper, manual analysis of their most critical assets.

We offer a full range of penetration testing services tailored to your attack surface:

• Web application penetration testing — OWASP Top 10 coverage plus business logic, authentication, and authorization testing.
• API security testing — REST, GraphQL, and SOAP API assessments for authentication bypass, injection, and data exposure.
• External network penetration testing — internet-facing infrastructure, services, and perimeter defenses.
• Internal network penetration testing — lateral movement, privilege escalation, and Active Directory attacks from an assumed-breach position.
• Cloud security assessments — AWS, Azure, and GCP configuration reviews and attack-path analysis.
• Mobile application security testing — iOS and Android app analysis including local storage, API communication, and binary protections.

The penetration testing process typically takes one to three weeks of active testing, depending on scope and complexity. A focused web application test may take five to seven business days, while a large-scope internal network assessment or red team operation can run two to four weeks.

Our full pentest timeline from start to finish looks like this: scoping and planning (two to three days), active testing (one to three weeks), report writing and quality review (three to five days), and findings delivery with a walkthrough call. We also include a retest window after your team has remediated the findings.

Our penetration testing company follows industry-recognized methodologies including OWASP (Open Web Application Security Project) Testing Guide, PTES (Penetration Testing Execution Standard), and NIST SP 800-115 for technical security testing. These frameworks ensure thorough, repeatable, and standards-aligned testing across every engagement.

Beyond methodology, our team members are active bug bounty researchers who continuously discover vulnerabilities in production systems across major platforms. This real-world offensive experience — combined with structured methodology — means our testing reflects how actual attackers operate, not just how textbooks say they should.

Penetration testing cost depends on the scope, complexity, and type of engagement. A focused web application pentest for a small to mid-size application typically starts in the low-to-mid four figures, while comprehensive network assessments and red team operations for larger environments fall in the mid-to-high four figures or above.

We provide transparent, fixed-price proposals after an initial scoping call — no surprise fees. Factors that influence pentest pricing include the number of targets or applications, testing depth (black-box, gray-box, or white-box), compliance requirements, and whether retesting is included.
