In today’s rapidly evolving threat landscape, understanding and mitigating your digital vulnerabilities isn’t just an option—it’s a necessity. At Brinztech, we offer comprehensive Vulnerability Assessment and Penetration Testing (VAPT) services designed to pinpoint weaknesses across your entire IT infrastructure. Our expert team simulates real-world attacks and employs a meticulous approach, from broad vulnerability assessments to deep-dive exploitation, ensuring we uncover weaknesses before malicious actors can exploit them.

Our Vulnerability Assessment & Penetration Testing (VAPT) Services

We provide a range of specialized assessments, each tailored to specific areas of your infrastructure. This targeted approach ensures no stone is left unturned in safeguarding your systems.

Vulnerability Assessment

Objective: Proactively identify a wide range of security weaknesses within your systems, networks, and applications using automated and manual techniques. This provides a broad overview of potential vulnerabilities that could be exploited.

Our vulnerability assessment service includes:

• Network Vulnerability Assessment:

  We scan your internal and external networks to detect misconfigurations, open ports, default credentials, and known vulnerabilities in network devices and services.

• Web Application Vulnerability Assessment:

  Automated and manual checks of your web applications to identify common flaws like SQL Injection, Cross-Site Scripting (XSS), and insecure configurations.

• System and Server Vulnerability Assessment:

  We assess operating systems and installed software for known Common Vulnerabilities and Exposures (CVEs) and insecure patches.

• Reporting & Prioritization:

  You’ll receive a detailed report outlining identified vulnerabilities, their severity, and recommendations for remediation.

Tools: We utilize leading vulnerability scanners and assessment tools such as Nessus, OpenVAS, and Qualys to ensure comprehensive coverage.

1. Web Application Penetration Testing

Objective: Discover and exploit specific, deeper vulnerabilities within your web applications (beyond automated scanning capabilities), including complex SQL Injection (SQLi), Cross-Site Scripting (XSS), and advanced authentication bypasses.

Our process includes:

• Information Gathering:

  We enumerate subdomains, crawl your application for hidden paths, and check for exposed APIs to understand your web attack surface.

• Authentication & Session Testing:

  We test for brute-force vulnerabilities, session fixation/hijacking, and attempt to bypass multi-factor authentication (MFA).

• Input Validation & Injection:

  We rigorously test for SQL Injection, various forms of Cross-Site Scripting (Reflected, Stored, DOM), and Command Injection to uncover critical execution flaws.

• Security Misconfigurations:

  We identify default credentials, directory listings, and misconfigured HTTP headers (CORS, HSTS, CSP).

• Business Logic Flaws:

  Our team uncovers weaknesses in your application’s logic, such as price manipulation and privilege escalation.

• API Security:

  We identify vulnerabilities like Broken Object Level Authorization (BOLA) and excessive data exposure in your APIs.

Tools: We leverage industry-standard tools such as Burp Suite, OWASP ZAP, SQLmap, and Nikto for thorough analysis.

2. Internal Network Penetration Testing

Objective: Simulate an insider threat or a compromised device within your network to assess the impact and identify lateral movement opportunities.

Our internal network tests cover:

• Network Discovery:

  We perform ARP scanning and identify live hosts and open ports to map your internal network.

• Active Directory Exploitation:

  Our team tests for Kerberoasting, Pass-the-Hash vulnerabilities, and LLMNR/NBT-NS poisoning to compromise Active Directory environments.

• Privilege Escalation:

  We attempt to escalate privileges through kernel exploits (e.g., DirtyCow, Windows CVEs) and identify misconfigured services with weak permissions.

• Lateral Movement:

  We simulate techniques like RDP, PsExec, and WMI abuse, and attempt to dump credentials from memory (LSASS, SAM database).

Tools: Our toolkit includes CrackMapExec, Mimikatz, BloodHound, and Metasploit for in-depth internal network assessments.

3. External Network Penetration Testing

Objective: Evaluate the resilience of your organization’s perimeter defenses, including firewalls and publicly exposed services, against external attacks.

Our external testing methodology includes:

• Reconnaissance:

  We conduct WHOIS lookups, DNS enumeration, and use OSINT tools like Shodan and Censys to identify exposed devices.

• Port Scanning & Banner Grabbing:

  We use tools like Nmap to detect open ports, identify services, and pinpoint weak protocols (e.g., Telnet, FTP, SNMP).

• Firewall & IDS Evasion:

  We test techniques to bypass your perimeter defenses, including fragmented packets and timing attacks.

• Exploiting Public-Facing Services:

  Our experts attempt to exploit vulnerabilities in VPNs (Citrix, Pulse Secure), web servers (Apache, Nginx misconfigurations), and email servers (OpenSMTPD, Exchange flaws).

Tools: We utilize Nmap, Masscan, and Metasploit to thoroughly assess your external attack surface.

4. Cloud Penetration Testing (AWS/Azure/GCP)

Objective: Find misconfigurations and security vulnerabilities within your cloud environments (Amazon Web Services, Microsoft Azure, Google Cloud Platform).

Our cloud testing focuses on:

• IAM & Access Control:

  We identify overprivileged roles, exposed AWS S3 buckets, and vulnerable Azure Storage Account configurations.

• Serverless & API Testing:

  We analyze Lambda function flaws and API Gateway misconfigurations that could lead to unauthorized access.

• Kubernetes & Container Security:

  We look for exposed Kubernetes dashboards and assess Docker escape vulnerabilities.

• Logging & Monitoring Bypass:

  We test for disabled logging (e.g., AWS CloudTrail) and lack of critical security alerts (e.g., GuardDuty).

Tools: Our cloud-specific tools include Pacu (AWS), ScoutSuite, and CloudSploit to identify and report cloud-native vulnerabilities.

5. Wireless & IoT Penetration Testing

Objective: Uncover security weaknesses in your wireless networks and Internet of Things (IoT) devices.

Our specialized testing covers:

• Wi-Fi Testing:

  We perform handshake capturing, WPA2/WPA3 cracking, and test for Evil Twin attacks.

• IoT Device Testing:

  We conduct firmware analysis, search for default credentials, and perform hardware hacking techniques like UART/JTAG to gain access to embedded devices.

Tools: We use Aircrack-ng, Wireshark, and Flipper Zero to execute these specialized tests.

Our Post-Assessment Commitment

Our service doesn’t end with vulnerability discovery. We ensure you have a clear roadmap to strengthen your security posture:

1. Comprehensive Documentation:

   We provide detailed reports, including Proof of Concept (PoC) for each finding and corresponding CVSS scores, to illustrate the impact.

2. Risk Prioritization:

   We prioritize identified risks from Critical to Low, allowing you to address the most pressing issues first.

3. Actionable Remediation Steps:

   We offer clear and practical recommendations for remediation, such as patching systems or disabling unnecessary services.

4. Retesting & Validation:

   After you implement the fixes, we conduct retests to validate that the vulnerabilities have been successfully mitigated.
