Test Your Defenses the Way Attackers Would.

Penetration Testing is a controlled ethical hacking practice that simulates real attack scenarios. At Sera Brynn, our experienced consultants use defense-grade methodologies and industry-leading tools to uncover vulnerabilities, demonstrate exploits, and provide prioritized remediation guidance. This proactive testing helps you fortify your cybersecurity defenses before adversaries strike.

Penetration Testing Strengthens Your Organization By: 

  • Identifying exploitable weaknesses before adversaries do
  • Validating control effectiveness across environments
  • Strengthening resilience against sophisticated attack techniques
  • Reducing operational and financial exposure
  • Supporting defensible compliance outcomes

Fortify Your Defenses

Cyber attackers are constantly evolving, discovering new ways to exploit weaknesses. Sera Brynn's penetration testing services proactively identify vulnerabilities across your systems, applications, and processes. By simulating real-world attacks, we expose potential risks before adversaries do and provide clear, prioritized remediation guidance.

Internal Penetration Test

Internal penetration testing evaluates the security of your organization’s internal systems and applications — including databases, file servers, and email servers.  

Our experts replicate real-world attack scenarios to uncover vulnerabilities and entry points that could be exploited if an attacker were to gain access inside your network.

External Penetration Test

External penetration testing targets your organization’s outward-facing systems and applications, such as web servers, email servers, and firewalls.  

Our team simulates real-world attack techniques against these assets to uncover vulnerabilities and identify potential entry points that external attackers could exploit.

Web Application Penetration Test

We perform controlled testing on your web applications to uncover and safely exploit vulnerabilities, strengthening their security and reducing the risk of future attacks.

PCI Compliant Penetration Test

We identify vulnerabilities that could allow attackers to gain unauthorized access to credit card data.  

Our experts simulate targeted cyberattacks on your network infrastructure, applications, and all systems involved in the processing, storage, or transmission of payment information.

Cloud Pen Testing

Cloud platforms expand capability and risk simultaneously.

We assess AWS, Azure, and Google Cloud environments for misconfigurations, excessive privileges, exposed services, and lateral movement paths. Our testing evaluates infrastructure, identity controls, and cloud-native services to determine how an attacker could gain persistence or escalate access.

You receive prioritized findings and remediation guidance aligned to compliance and operational risk.

Manual Pen Testing

Automation detects vulnerabilities. Experts expose attack paths.

Our security professionals simulate real-world adversaries to uncover chained exploits, authentication weaknesses, and business logic flaws that tools overlook. This approach reveals how individual weaknesses combine to create material risk.

The result is defensible, high-confidence findings with clear, actionable remediation steps.

White Box, Gray Box, Black Box

Testing calibrated to your threat model.

  • White Box: Full visibility into architecture and credentials for comprehensive control validation.
  • Gray Box: Limited access simulating a partially compromised or insider-informed adversary.
  • Black Box: No prior knowledge, replicating an external attacker operating from reconnaissance to exploitation.

Each model delivers distinct insight into exposure across internal and external attack surfaces.

Automated Pen Testing

Scalable validation with measurable consistency.

Automated testing identifies known vulnerabilities, configuration weaknesses, and exposed services across environments. It enables recurring validation between full-scope manual engagements and supports continuous risk management.

When combined with expert-led testing, it delivers both breadth and depth of assurance.

The Pen Test Phases

Sera Brynn provides comprehensive penetration testing designed to meet regulatory and industry standards.  

Our testing process follows proven methodology, including planning, reconnaissance, vulnerability analysis, exploitation, and reporting. This structured approach gives organizations a clear view of potential weaknesses across their systems and processes, helping reduce the risk of security incidents and strengthen overall resilience.

Phase 1: Planning and Reconnaissance

We collect detailed information about the target system or network, including IP addresses, operating systems, applications, and potential vulnerabilities.

Phase 2: Scanning

We utilize automated tools to scan the target system or network for vulnerabilities, such as open ports, misconfigured applications, and other possible entry points.

Phase 3: Gaining Access

We attempt to exploit discovered vulnerabilities to determine whether they can be used to gain access to the target system or network.

Phase 4: Maintaining
Access

After initial access is achieved, we test whether it’s possible to maintain that access and escalate privileges to gain deeper control over the target system or network.

Phase 5: Analysis &
Reporting

Every incident is an opportunity to strengthen your security posture. We provide detailed post-incident reports, including insights and recommendations to fortify your defenses and minimize the risk of recurrence.

The Results

It is important to remember that penetration test results represent your security posture at a single point in time. To stay protected against evolving threats, organizations should conduct regular testing to identify and address new vulnerabilities.

Continuous Improvement

Cybersecurity is never static! Threats evolve every day. Regular penetration testing helps organizations stay ahead of emerging risks and maintain a strong security posture.

By simulating real-world attacks, penetration testing also strengthens incident response capabilities. It exposes gaps in existing response plans and provides valuable lessons to improve overall resilience.

Boost Client Confidence

A cyber attack can damage reputation, erode customer trust, and result in financial losses. Proactively identifying and addressing vulnerabilities shows a strong commitment to security and helps preserve your organization’s reputation.

Identify Vulnerabilities

We'll help you with SPRS (Supplier Performance Risk System) score submission by reviewing the NIST 800-171 assessment, providing guidance on SPRS score calculation, ensuring compliance with SPRS requirements, submitting the SPRS score to the DoD's SPRS database, and providing ongoing support.
