Cybersecurity that earns the ATO.
NIST SP 800-53 and DoD RMF aren't templates we fill in, they're the operating model. From cybersecurity maturity assessment through ATO authoring and continuous monitoring, we deliver a defensible posture that the authorizing official, the OIG, and the workforce can all live with.

InterScripts provides federal cybersecurity and Zero Trust services built on NIST SP 800-53 and DoD RMF. The work runs from cybersecurity maturity assessment and penetration testing through threat hunting, incident response, ATO authoring and continuous monitoring. InterScripts is a Minority-Owned, DBE-certified company with CAGE 8YC07 and a GSA MAS contract.
Domains
Cybersecurity and Zero Trust domains
Maturity Assessment & Gap Analysis
NIST CSF and CIS-aligned cybersecurity maturity assessment. Gap analysis against the controls your authorizing official will actually score against. POA&M-ready findings with prioritized remediation roadmap.
- NIST SP 800-53 control assessment, baseline-aware
- DoD RMF artifact readiness and traceability
- Penetration testing, internal, external, and assumed-breach
- Active Directory hardening and identity hygiene
Cyber Defense, Zero Trust, and Threat Hunting
Mature defense capabilities across critical infrastructure. Threat hunting program with telemetry-driven hypotheses. Data-loss prevention and insider-threat controls that don't paralyze the workforce.
- Zero Trust Architecture, identity, device, workload, data
- EDR, SIEM, and SOAR tuning for real-world signal
- Threat intelligence integration and threat-hunt cadence
- DLP and insider-threat controls calibrated to mission risk
Incident Response & Digital Forensics
IR plans that map to your specific business processes, retention obligations, and notification timelines. Investigation under privacy and chain-of-custody discipline. Compromise assessment to minimize dwell time.
- IR planning aligned to NIST SP 800-61 and agency policy
- Forensic acquisition and analysis with chain-of-custody
- Compromise assessment and dwell-time reduction
- Tabletop exercises and post-incident lessons-learned
ATO Readiness & Continuous Monitoring
System Security Plan, Security Assessment Report, POA&M, written so the AO finds the answers, not the questions. Continuous monitoring program that survives the first re-authorization with the same artifacts.
- SSP, SAR, POA&M, contingency plan, and IRP authoring
- Independent assessor coordination: 3PAO interface
- Continuous monitoring program and quarterly reporting
- Re-authorization preparation and inheritance optimization
Compliance-Built Posture
Federal-Grade Security Credentials
InterScripts maintains the highest certification levels and regulatory standards to ensure safety, security, and compliance for every client.

What do agencies ask about cybersecurity and Zero Trust?
Which cybersecurity frameworks does InterScripts work in?
NIST SP 800-53 (Rev 5), NIST CSF 2.0, CIS Controls v8, DoD RMF, FedRAMP Moderate / High, CMMC Level 2, NIST SP 800-66 for healthcare workloads, and Zero Trust Architecture aligned to CISA and DoD reference architectures.
Does InterScripts perform penetration testing?
Yes. Internal, external, and assumed-breach penetration testing, plus red-team and purple-team exercises tied to MITRE ATT&CK coverage maps. Reports are POA&M-ready and traceable to the controls your authorizing official will score against.
Can InterScripts help us achieve ATO?
Yes. The team prepares System Security Plans (SSPs), Security Assessment Reports (SARs), Plans of Action and Milestones (POA&Ms), and continuous-monitoring artifacts to support agency ATO processes. Common targets: FedRAMP Moderate, FedRAMP High, IL4 / IL5, agency RMF.
How does InterScripts approach Zero Trust?
Zero Trust is treated as an operating model, not a product. The reference design covers identity (ICAM with PIV / CAC), device (compliance attestation, posture), network (segmentation, micro-perimeter), application (least privilege, JIT), data (classification, tagging, DLP), and visibility (CDM-aligned telemetry, SIEM, SOAR).
