NIST compliance services — alignment for government contractors and regulated entities.
NIST frameworks establish the benchmark for cybersecurity risk management, particularly for organisations working with US government agencies, defence-adjacent supply chains, or federal contracting relationships. SIRI Law LLP delivers NIST CSF 2.0, SP 800-53 Revision 6, and AI RMF alignment, with the newly merged Cyber AI Profile built into scope from the outset.
Getting the current framework state right
SP 800-53 quietly moved to Revision 6, and the Cyber AI Profile is no longer a separate document — it's built into CSF 2.0 itself.
NIST compliance content often references "SP 800-53" without a revision number, as if the standard were static. It isn't. SP 800-53 moved to Revision 6 in early 2026 — the most significant change to the control catalogue since Revision 5 integrated privacy controls directly alongside security controls. Revision 6 places new emphasis on automated control verification and expands supply chain risk management requirements, reflecting the same software-supply-chain concerns driving parallel changes across other frameworks this year. An organisation whose control mapping was built against Revision 5 should have that mapping actively reviewed, not assumed to still be current, particularly anywhere automated evidence collection or vendor risk controls are in scope.
The more structurally significant change is what's happened to AI-specific guidance. NIST began circulating a preliminary draft "Cyber AI Profile" for public comment in late 2025 and early 2026 — a CSF 2.0 extension addressing three angles of AI risk: securing AI components themselves, using AI defensively, and countering AI-augmented attacks. What's changed since is that NIST has merged this profile directly into the core Cybersecurity Framework rather than keeping it as an optional standalone addendum. As of mid-2026, the Govern function — the newest of CSF 2.0's six core functions — now explicitly expects organisations in scope to map AI dependencies and document model lineage (the origin and training data behind any deployed AI system) as part of ordinary CSF 2.0 alignment work, not as a separate AI-specific exercise bolted on afterward.
For any organisation with an existing NIST-aligned control set, the practical takeaway is straightforward: a control mapping frozen at CSF 2.0's 2024 launch or SP 800-53 Revision 5 is not automatically wrong, but it is genuinely dated in two specific, checkable ways — Rev 6's supply chain and automation emphasis, and the Govern function's now-explicit AI dependency mapping requirement.
Which framework applies
Three NIST frameworks, three different purposes
Most organisations need one, not all three. We assess which combination fits your contractual and regulatory context.
CSF 2.0
The overall risk management structure — Govern, Identify, Protect, Detect, Respond, Recover. Right starting point for most organisations, including those with no US federal relationship.
SP 800-53 Rev 6
Specific, detailed control implementation. Relevant when you must demonstrate control-level compliance, typically for federal contracting or CUI-handling relationships.
AI RMF / Cyber AI Profile
Relevant if you develop or deploy AI systems — increasingly addressed through CSF 2.0's Govern function directly, rather than as a standalone framework engagement.
Evidence, not guesswork
SP 800-53 Revision 5 vs. Revision 6 — what actually changed
If your control mapping predates early 2026, this is what needs review.
| Dimension | Revision 5 | Revision 6 |
|---|---|---|
| Headline change | Privacy controls integrated directly into the security control catalogue | Automated verification and expanded supply chain risk management |
| Evidence expectation | Manual and automated evidence both accepted | New emphasis on automated, continuously verifiable control evidence |
| Supply chain scope | Baseline supply chain risk management controls | Expanded controls addressing software component integrity specifically |
| Effective | 2020, amended through 2023 | Early 2026 |

Scope of services
What our engagement covers
Framework selection, control implementation, evidence programme design, and ongoing alignment as NIST guidance evolves.
Framework Selection & Scoping
Assessment of which NIST framework — or combination — applies to your specific contractual and regulatory context, avoiding unnecessary duplicate effort.
CSF 2.0 Gap Assessment
Assessment across all six core functions — Govern, Identify, Protect, Detect, Respond, Recover — including the now-mandatory AI dependency mapping under Govern.
SP 800-53 Rev 6 Control Implementation
Control-by-control implementation and documentation against the current Revision 6 catalogue, including the expanded automated-verification and supply-chain requirements.
AI Governance & Model Lineage
Documentation of AI dependencies and model lineage to satisfy the Cyber AI Profile's now-merged requirements within CSF 2.0's Govern function.
Evidence Programme Design
Automated and manual evidence collection calibrated to current NIST expectations, avoiding the gap between a static control document and demonstrable operating evidence.
Cross-Framework Mapping
NIST alignment mapped alongside CERT-In, RBI, and DPDPA obligations, so Indian regulated entities avoid building duplicate, disconnected compliance programmes.
What the numbers actually mean
Four figures that frame NIST alignment today
Govern, Identify, Protect, Detect, Respond, Recover — Govern added in 2.0 as the newest, now carrying AI dependency mapping too.
Effective early 2026 — automated verification and expanded supply chain controls are the headline changes.
Despite frequent references to one — the real shift is the Cyber AI Profile merging into CSF 2.0 directly.
As of the February 2026 anniversary — still the current, operative framework version.

Integration advantage
NIST alignment backed by qualified legal counsel
Our compliance engagements ensure your programme satisfies both US federal expectations and Indian legal obligations under DPDPA, IT Act, and sector-specific regulation.
We track revision changes, not just framework names
We flag when SP 800-53 moves revisions or when guidance like the Cyber AI Profile gets merged into the core framework, rather than leaving clients working from a control mapping that's quietly gone stale.
NIST alongside Indian frameworks, not instead of them
Our legal team maps NIST controls against CERT-In, RBI, and DPDPA obligations simultaneously, avoiding the duplicate compliance work most standalone NIST consultants create for Indian entities.
AI dependency mapping built in from the start
Since the Cyber AI Profile now sits inside CSF 2.0's Govern function, we scope AI dependency and model lineage documentation as part of the core engagement, not a separate add-on.
Certified engineers
Our team holds CCSP, CISM, CIPP/E, CEH, OSCP, CISSP, CPENT, and ISO 27001 Lead Auditor credentials, the mix that federal contracting reviewers and Indian regulators both expect to see.
Frequently asked
NIST compliance, answered directly
Is NIST compliance mandatory for Indian companies?
NIST frameworks are US federal standards, not mandatory under Indian law. However, Indian companies working with US government agencies, US federal contractors, or defence-adjacent supply chains often need to demonstrate NIST alignment contractually. Many Indian organisations also voluntarily adopt NIST CSF 2.0 as a comprehensive risk management framework independent of any US contractual requirement, since it maps cleanly onto CERT-In and RBI expectations.
Has SP 800-53 changed recently, and does that affect an existing programme?
Yes. SP 800-53 moved to Revision 6 in early 2026, the most significant update since Revision 5 integrated privacy controls directly into the catalogue. Revision 6 places new emphasis on automated control verification and expands supply chain risk management requirements. Organisations whose control mapping was built against Revision 5 should have that mapping reviewed rather than assumed to still be current, particularly where automated evidence collection or vendor risk controls are in scope.
What is the Cyber AI Profile, and is it now part of CSF 2.0 itself?
The Cyber AI Profile began as a preliminary draft NIST circulated for comment in late 2025 and early 2026, addressing AI-specific risks: securing AI components, using AI for defensive purposes, and countering AI-augmented attacks. As of mid-2026, NIST has merged the profile into the core Cybersecurity Framework rather than keeping it as a standalone addendum, meaning the Govern function now explicitly expects organisations to map AI dependencies and document model lineage, the origin and training data behind any AI system in scope, as part of ordinary CSF 2.0 alignment, not as optional supplementary guidance.
Which NIST framework should we start with?
CSF 2.0 is the right starting point for most organisations — it provides the overall risk management structure. SP 800-53 becomes relevant if you need to demonstrate specific control implementation, typically for federal contracting relationships. AI RMF, now largely absorbed into CSF 2.0's Govern function via the Cyber AI Profile, is relevant if you develop or deploy AI systems. We assess which combination applies to your specific contractual and regulatory context.
Does NIST alignment help with ISO 27001 or SOC 2 at the same time?
Yes, substantially. NIST CSF 2.0, ISO 27001, and SOC 2's Security TSC share significant control overlap. Organisations pursuing multiple frameworks benefit from a combined control mapping exercise rather than three separate, disconnected assessments — we design engagements to capture this overlap wherever it exists.
How often does NIST guidance actually change?
More often than most compliance programmes account for. Beyond major revisions like SP 800-53 Rev 6, NIST continuously publishes new Informative References mapping CSF 2.0 to other standards — including a new OWASP LLM Top 10-to-CSF crosswalk published in April 2026 — plus interim reports, workshop outputs, and draft profiles under active development. A programme reviewed once at implementation and never revisited will drift out of alignment within a year or two.
