Digital Forensics — Find out exactly what happened, with evidence that holds up
After a suspected breach or insider incident, SIRI Security's forensics team preserves evidence properly, reconstructs exactly what happened, and — where needed — produces reporting that stands up in court or before a regulator.
Depth, held to an evidentiary standard
What is Digital Forensics investigation?
Digital forensics is the disciplined process of preserving, analysing, and documenting digital evidence after a suspected incident — a breach, insider threat, fraud, or data theft — in a way that answers what actually happened and, where needed, holds up as evidence.
Chain of custody matters as much as technical skill here: evidence handled incorrectly can become inadmissible even if the technical findings are correct. Our forensics work is coordinated with SIRI Law LLP wherever the outcome may end up in litigation, a regulatory filing, or a CERT-In notification.
SIRI Security delivers Digital Forensics 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 that undermine advanced assessment work
Depth without the right evidentiary discipline can end up unusable when it matters most.
“We'll worry about admissibility later”
Evidence collected without proper chain-of-custody discipline from the start often can't be rehabilitated afterward — the Bharatiya Sakshya Adhiniyam 2023 cares about how it was gathered, not just what it shows.
“Standard VAPT already covers this”
Red-team operations, AI/LLM audits, hardware security, and digital forensics each require specialised methodology that routine testing doesn't attempt.
“New technology just needs the same checklist”
AI/LLM systems and specialised hardware introduce failure modes — prompt injection, model extraction, physical debug exposure — that generic assessment frameworks weren't built for.
“We can take our time on a complex finding”
CERT-In's notification clock doesn't pause for investigative complexity — advanced assessment work still has to feed a fast decision process.
What Digital Forensics covers
What's included, start to finish
Depth-first work, documented to a standard that holds up beyond the engagement itself.
Evidence preservation & chain of custody
Forensically sound imaging and documentation from the first response onward.
Timeline reconstruction
Rebuilding exactly what happened, when, and by whom or what, from available artefacts.
Root cause analysis
How the incident actually started, not just what it touched.
Malware & artefact analysis
Reverse-engineering any malicious tooling found on affected systems.
Legally-coordinated reporting
Findings structured for litigation, regulatory filing, or insurance claims where relevant.
Evidence, not guesswork
Generic assessment vs. a documented SIRI engagement
The difference shows up when findings need to go somewhere — a board, a regulator, or a court.

Why SIRI for Digital Forensics specifically
Depth backed by an evidentiary standard, under one roof
The same team that runs the assessment can carry a real finding into a legal or regulatory response without a handoff.
Court-admissible from the first byte collected
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.
Led by named offensive-security practitioners
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
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 the Bharatiya Sakshya Adhiniyam's standard
Evidence handling is designed to the admissibility standard India's evidence law sets, not a generic international template retrofitted afterward.

How we work
From scoping to ongoing delivery
Evidence Preservation
Immediate, forensically sound preservation of affected systems and logs before anything else is touched.
Week 1Analysis & Timeline Reconstruction
Detailed analysis of preserved evidence to reconstruct the incident timeline and root cause.
Weeks 2–3Attribution & Scope Assessment
Establishing what was actually accessed or exfiltrated, and by what means.
Week 4+Reporting
A findings report structured for its intended use — internal remediation, litigation, regulatory filing, or insurance.
OngoingFrequently asked
Digital Forensics, answered directly
Can this support a legal case or insurance claim?
Yes — where litigation, regulatory action, or an insurance claim is likely, we coordinate directly with SIRI Law LLP so evidence handling and reporting hold up.
How fast can you respond?
Our emergency response protocol activates within 15 minutes of your call, 24/7, for active or suspected incidents.
How long does this take?
Most engagements in this category run 1 to 3 weeks depending on scope; we'll give you an exact estimate once scoping is complete.
Who actually does the work?
Senior SIRI Security specialists carry out every engagement personally — this is never outsourced or run purely by automated tooling.
