Threat Modeling — Model the threats specific to your architecture, not a generic checklist
SIRI Security conducts structured threat modeling against your specific systems and architecture, identifying realistic attack paths before they're built, tested, or exploited.
Tested at the standard a real adversary would use
What does Threat Modeling involve?
Generic security checklists miss the threats that are specific to how your particular systems, data flows, and architecture actually work. Threat modeling is the structured discipline of mapping out exactly how an adversary could realistically attack your specific environment.
We use established methodologies (STRIDE, attack trees, or a methodology suited to your context) to map data flows, trust boundaries, and attack paths, producing a prioritised view of where design-level security investment matters most.
SIRI Security delivers Threat Modeling to this standard directly — practitioner-led, documented, and connected to SIRI Law LLP's legal and regulatory response if a finding ever needs to go further.
What organisations get wrong
Four assumptions elite-tier assessment exists to correct
Routine testing answers 'did we pass'; elite assessment answers 'could we actually survive this.'
“Our standard testing programme already covers this”
Elite-tier assessment goes further than routine testing by design — chaining findings the way a real, motivated adversary would, not stopping at the first clean scope boundary.
“We'd cope fine if ransomware hit us”
Ransomware readiness untested is ransomware readiness assumed — and 70% of malware detections are trojans and file infectors (Seqrite 2026), the common precursor.
“Generic threat intelligence is specific enough”
A threat model built around your actual environment, assets, and adversary incentives finds what generic industry threat feeds miss.
“The findings are just for our internal team”
Where an elite assessment surfaces something serious, the way it was documented matters if it ever needs to support a legal or insurance position.
What Threat Modeling covers
What's included, start to finish
Assessed the way a real, motivated adversary would approach it — not a generic checklist.
Architecture & data flow mapping
A clear map of how data and trust flow through your systems.
Structured threat identification
STRIDE or an equivalent methodology applied systematically, not ad hoc.
Attack path prioritisation
Threats ranked by realistic likelihood and impact, not treated as equally urgent.
Design-stage recommendations
Security controls recommended at the architecture level, where they're cheapest to fix.
Developer & architect workshop
A working session with your technical team to embed the findings.
Evidence, not guesswork
Routine testing vs. self-assessed confidence vs. a SIRI elite assessment
The difference shows up exactly when a real, sophisticated threat actually arrives.

|---|---|---|---|
| Attacker's-POV methodology | No | No | Included |
| Ransomware readiness tested | No | Assumed | Verified directly |
| Custom threat model | No | Generic feeds only | Built for your environment |
| Evidentiary documentation | N/A | Informal | Litigation-ready where relevant |
| Executive narrative reporting | No | Rare | Included |

Numbers every board should know
What elite-tier assessment is actually catching
Of cloud detections
Trace to misconfiguration and IAM exploitation (DSCI).
Of malware detections
Are trojans and file infectors (Seqrite 2026) — the common ransomware precursor.
Incidents CERT-In handled
In the latest reporting year — the scale elite assessment work is measured against.
CERT-In notification window
The deadline a tested readiness posture is built to meet.
Why SIRI for Threat Modeling specifically
Assessed by the same team that runs real incident response
The practitioners who run elite assessments are the same ones who contain real breaches — not a separate red-team vendor with no downstream accountability.
Led directly by SIRI's Head of Cybersecurity
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
Court-admissible findings when it matters
Ananya Krishnan, SIRI's Digital Forensics Lead, prepares court-admissible forensic reports and testifies as an expert witness when findings end up in front of a judge.
Findings connected directly to legal exposure
SIRI Security runs under the same roof as SIRI Law LLP — when a finding carries real legal exposure, the engagement can be brought under attorney-client privilege from day one, not bolted on after the fact.
Built for RBI's specific resilience bar
Assessment scope and reporting are built to the standard RBI's 2026 Framework expects from regulated entities, not a generic red-team template.

Organisations this elite assessment service is built for
How we work
From scoping to ongoing delivery
Scoping & Rules of Engagement
We define scope, objectives, and rules of engagement together, so the exercise targets what actually matters to your business.
Week 1Assessment Execution
Our senior team executes the assessment, simulating realistic adversary behaviour rather than a generic scanner run.
Weeks 2–3Findings & Debrief
We walk your team through findings in a live debrief, not just a written report dropped in an inbox.
Week 4+Remediation Roadmap
A prioritised roadmap ties every finding to a concrete next step, ranked by actual risk.
OngoingFrequently asked
Threat Modeling, answered directly
Is this only for new systems being designed?
It's most valuable early in design, but is equally useful applied retroactively to existing systems to find overlooked attack paths.
Which methodology do you use?
We typically use STRIDE or attack-tree analysis, adapted to your architecture and the threats most relevant to your industry.
How long does this take?
Most engagements in this category run 3 to 6 weeks depending on scope, with senior specialists involved throughout.
Who on our side needs to be involved?
We typically work with your security lead and relevant technical owners; for tabletop-style exercises, leadership involvement is part of the value.
Test the assumption, not just the perimeter
Scope Threat Modeling.
Most engagements start with a short scoping call to agree objectives and rules of engagement.
