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 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 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.
How Pluto Security Conducts Government Security Testing
Our federal agency pen test methodology follows NIST 800-115 technical guide and aligns with FISMA, FedRAMP, and CMMC documentation requirements at every step.
- 1
Authorization and Scoping, We work within your rules of engagement, coordinate with your ISSO or security team, and define scope to meet your specific authorization framework requirements.
- 2
NIST 800-53 Penetration Testing, Systematic testing of technical controls mapped to NIST 800-53 control families including access control, configuration management, and system and communications protection.
- 3
FedRAMP Penetration Testing, Cloud infrastructure and application testing following FedRAMP Annual Penetration Test Guidance, covering the cloud boundary and authorization boundary assets.
- 4
CMMC Penetration Testing, Assessment of CUI handling environments against CMMC Level 2 and Level 3 practice requirements, with findings linked to specific practice IDs.
- 5
Government-Ready Reporting, Deliverables are formatted to support Plan of Action and Milestones documentation, risk acceptance decisions, and reauthorization processes.

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.
Authentication bypass via JWT signature confusion
Proof of concept
POST /api/session HTTP/1.1
Authorization: Bearer <alg:none forged token>
-> 200 OK role=adminRemediation
Pin a fixed signing algorithm server-side and reject alg:none. Retested and confirmed fixed.
