Cybersecurity, Analysis &
Assessment Expertise.

ACS brings cybersecurity, technical analysis, adversarial testing, and secure engineering together to determine how complex systems behave in practice, measure how their defenses perform, and produce evidence decision makers can use.

Where This Comes From

It starts with testing high-assurance security boundaries.

ACS’s offensive and assessment expertise is grounded in work performed by ACS personnel on policy bypass testing of cross-domain solutions. The work supported a national-level government sponsor at the Integrated Test & Evaluation Center (ITEC) at AFRL Rome under contract through defense prime contractors.

Cross-domain solutions exist to enforce a single guarantee: that only permitted data crosses a security boundary. Testing that guarantee requires more than an external view. Assessors must establish what the control inspects, what assumptions its implementation makes, and where its interpretation of a file format or network protocol diverges from the specification. Much of that behavior must be established from the system itself.

Assessors then demonstrate the consequence and document it as evidence measured against NIST 800-53 that can withstand government review.

ACS approaches assessment engagements the same way: examine the system as implemented, validate the finding, and document the result so another qualified team can reproduce it.

The Operating Model

Reverse engineering
established what the control inspected

Red teaming
demonstrated what it missed

Test and evaluation
turned the result into evidence a program office could defend and act on

That work established the operating model that connects ACS’s assessment capabilities.

Capability Areas

Five areas of expertise.

Red Teaming & Offensive Cyberspace Operations

Multi-domain offensive operations: offensive cyber, exploit and tool development, vulnerability assessment, reconnaissance and attack planning, physical security assessment, and evaluation of Blue team capability.

Reverse Engineering

Vulnerability research and reverse engineering (VR/RE) across binaries, file formats, protocols, mobile applications, and the configuration and policy of fielded integrated systems.

Explore Reverse Engineering →

Test & Evaluation

Cyber T&E and adversarial assessment, NIST 800-53 security control assessment, test planning and procedures, and independent assessment reporting, including policy bypass testing of security filtering and data transfer systems.

Cybersecurity

Security engineering and compliance across NIST 800-53 and 800-171, RMF and ATO navigation, STIG and CIS hardening, FedRAMP and FIPS-140, SIEM and log analytics, and DevSecOps.

Explore Cybersecurity →

Software Engineering

Secure software development across mobile applications, backend services and APIs, and cloud-native systems on AWS, informed by engineers experienced in both building and assessing systems.

The Through-Line

Five capabilities, one evidence-driven approach.

These capabilities are often delivered independently. ACS connects them so requirements, system behavior, adversarial findings, assessment evidence, and remediation inform one another.

STEP 01

Cybersecurity defines the requirement

Security engineering and compliance establish the controls, threat context, and authorization objectives a system has to satisfy.

STEP 02

Reverse engineering establishes actual behavior

Analysis shows how software, interfaces, formats, and integrated systems work in practice, including where implementation differs from documentation.

STEP 03

Red teaming validates consequence

Authorized offensive activity demonstrates whether a weakness is exploitable and measures what defensive capabilities detect, miss, and report.

STEP 04

Test and evaluation produces defensible evidence

Disciplined planning, procedures, and reporting turn results into artifacts an assessor or decision maker can review and reproduce.

STEP 05

Software engineering closes the loop

Engineers experienced in both building and assessing systems can translate findings into stronger designs, implementations, and remediation.

How We Work

Credentialed, cleared, and structured to team.

Credentials

✓  ACS personnel bring 25 years across software engineering and cybersecurity
✓  ACS personnel hold OSCP and CISSP credentials and an MS in Information Assurance
✓  Methodology aligned to NIST 800-53, OWASP, and MITRE ATT&CK
✓  Experience leading government and defense test teams, and penetration testing of a DoD agency end to end
✓  Prior engineering roles at major defense primes, supporting government programs in Rome, NY
✓  Cleared personnel are available for classified engagements

Teaming Readiness

ACS is structured to work as a cleared subcontractor and can own a defined work package: scope, execution, and deliverables inside a larger program, with artifacts written to the prime’s or the sponsor’s standard.

For primes assembling a team, ACS is a specialist subcontractor rather than a generalist: cross-domain and high-assurance assessment, software and systems VR/RE, offensive security, and cyber T&E.

Scope

Specialist scope and teaming boundaries.

Clear scope makes technical teaming more effective. ACS defines its specialist lanes up front and teams with complementary providers when a program requires capabilities outside them.

VR/RE Lane

Covers software and integrated systems: binaries, file formats, protocols, mobile applications, configuration and policy. Hardware, firmware, and embedded RE sit outside our lane and are best addressed by teaming.

Offensive Domains

Offensive work spans cyber and physical domains. ACS does not claim spectrum operations.

T&E Focus

T&E is developmental and security assessment focused. ACS does not claim operational test and evaluation.

Who We Serve

Expertise applied where the consequences are real.

DoD & Program Offices

Assessment, evaluation, and engineering support for programs that must evidence security posture to a decision maker or an assessor.

Prime Contractors & Teaming

A cleared specialist subcontractor for offensive, VR/RE, and T&E scope inside a larger program.

Federal Civilian & Law Enforcement

Independent testing, assessment, and analysis for agencies that need to know what their systems enforce.

Commercial & Critical Infrastructure

Cybersecurity, software assurance, and independent assessment for organizations operating high-consequence systems.
