Federal Penetration Testing Services USA

Pluto Security delivers federal penetration testing services USA covering FISMA penetration testing, FedRAMP penetration testing, CMMC penetration testing, and NIST 800-53 assessments for government agencies and contractors.

// Why it matters

Why Government Agencies and Contractors Need Specialized Penetration Testing

Government systems and contractor networks are among the most targeted environments in the world. Nation-state actors, ransomware groups, and insider threats all pursue federal and public sector organizations for the sensitive data and operational access they hold. Our federal penetration testing services USA are designed for the rigorous requirements of government environments.

FISMA Penetration Testing

We test federal information systems against NIST 800-53 controls to support your FISMA authorization package and continuous monitoring requirements.

FedRAMP Penetration Testing

Our assessments follow FedRAMP penetration testing guidance, supporting cloud service providers pursuing authorization for federal government use.

CMMC Penetration Testing

We help defense contractors meet CMMC Level 2 and Level 3 assessment requirements by testing the controls protecting Controlled Unclassified Information.

// The stakes

The Stakes of Cybersecurity in the Public Sector

The Stakes

Government cybersecurity testing is not optional when national security, citizen data, and operational continuity are on the line. Here is what inadequate testing risks.

Nation-State Threats

Nation-state actors specifically target federal agency systems for intelligence value.

Authorization to Operate

FISMA non-compliance can result in loss of authorization to operate.

Contract Risk

Government contractor cybersecurity testing failures can trigger contract termination under CMMC.

Citizen Services

Public sector penetration testing protects citizen services from ransomware-driven downtime.

Evidence Base

NIST 800-53 penetration testing provides the evidence base for your authority to operate.

Misconfigurations

Government systems security assessment uncovers misconfigurations before adversaries do.

// Proof, not a scan dump

Evidence Your Engineers Can Act On

Every finding ships with a severity rating, CVSS score, the affected asset, and reproducible proof-of-concept, validated by hand, never a raw scanner result. You fix it, we retest, and the report is updated to reflect resolved findings.

CriticalPLT-0142 · CVSS 9.1

Authentication bypass via JWT signature confusion

Asset: api.acme.com● Verified by hand

Proof of concept

POST /api/session HTTP/1.1
Authorization: Bearer <alg:none forged token>
-> 200 OK   role=admin

Remediation

Pin a fixed signing algorithm server-side and reject alg:none. Retested and confirmed fixed.
