Penetration Testing Services

Penetration testing, often called “pen testing,” is a simulated cyberattack on your systems, networks, web applications, or cloud infrastructure to identify vulnerabilities before real hackers can exploit them. At Varyence, we use a hybrid approach combining AI tools, automated tools (like Nmap, Burp Suite, and OWASP ZAP), and manual expertise to mimic real-world threats, ensuring comprehensive coverage. This helps protect sensitive data, meet compliance standards like PCI DSS, SOC 2, HIPAA, and ISO 27001, and build customer trust. 

Performing penetration testing follows a structured methodology, such as the Penetration Testing Execution Standard (PTES). 

Key phases include: 

• Scoping & Planning: Define scope and type of pentest, sign NDA/contract. 
• Reconnaissance: Gather public data (DNS, subdomains, ports) via OSINT for attack surface mapping. 
• Automated Scanning: Use tools to spot known vulnerabilities and misconfigurations for a quick baseline. 
• Manual Testing & Exploitation: Experts exploit flaws (SQL injection, auth bypasses) that tools miss, validating real impacts. 
• Analysis & Reporting: Detail finding such as vulnerabilities, risks (CVSS), impacts, and fixes. 
• Remediation & Re-Testing: Fix issues, then re-scan (in 30-60 days). 

• External Testing (Black-Box): Simulates attacks from outside your network (for example, public-facing web apps). 
• Internal Testing (White-Box): Tests from within your network, assuming an insider or compromised device. 
• Web Application Testing: Focuses on apps for issues like XSS or injection flaws. 
• Infrastructure/network testing: Test servers, network services, configurations, firewalls, network-level vulnerabilities. 
• Cloud Testing: Evaluates AWS, Azure, or GCP configurations. 

Varyence offers tailored penetration testing, from basic automated scans for small apps to enterprise-level manual testing with ongoing support and managed cybersecurity services for complex environments. 

There’s no one-size-fits-all answer but common practice is to test: 

• Before major releases or updates (new features, new infrastructure, architectural changes). 
• Periodically (annually, bi-annually, quarterly), especially if you handle sensitive data or are subject to compliance requirements.  
• After major changes (in codebase, infrastructure, deployment environment, integrations, etc.).  

A vulnerability scan is automated and identifies potential weaknesses (for example, outdated software) but doesn’t exploit them. Penetration testing goes further by actively exploiting vulnerabilities to demonstrate real impact, including manual validation to avoid false positives.  

A quality pen testing report covers: 

• Executive summary with risk overview. 
• Detailed vulnerability list with severity ratings (high/medium/low). 
• Proof-of-concept exploits and screenshots. 
• Business impact analysis. 
• Remediation steps and timelines. 

Varyence reports highlight common findings like weak SSL/TLS ciphers or missing security headers, plus tailored advice for your stack. See an example of a sample pen test report here. 

A well-planned penetration test especially from a reputable pen-testing company uses controlled methods to avoid disrupting normal operations. Unlike brute-force attacks, ethical pentesters try to minimize risk.

Still, in some cases (for example very aggressive exploitation, legacy systems, production environments) there may be risks, which is why it’s critical to define scope and get agreement on the rules of engagement beforehand.  

Keep in mind, hackers are constantly scanning and trying to penetrate your environment. 

When you are choosing a penetration testing company, look for: 

• Hybrid automated-manual methods to minimize false positives. 
• Transparent pricing and quick turnaround. 
• Reviews and compliance expertise. 
• Industry experience in your sector (e.g., AI, fintech, healthcare). 

Varyence is penetration testing company that excels in customized, HIPAA and SOC 2-compliant testing for AI, SaaS and enterprise software. We prioritize no-lock-in contracts and rapid delivery to fit your needs. 

Beyond compliance, pen testing prevents breaches costing an average of $4.4 million (Cost of Data Breach Report 2025 by IBM). It uncovers hidden risks, strengthens defenses, and demonstrates security maturity to stakeholders. Proactive pen-testing saves time and money long-term. 

Post-test, prioritize fixes based on severity, then rescan to verify. Varyence provides remediation guidance and optional ongoing support, including virtual CISO services, cybersecurity services, development services, and compliance services, to help you track vulnerabilities and maintain compliance.
