Inside Hidden Door

A private investigation agency working out of Guwahati since 2018 — field operatives, forensic analysts and legal-support specialists running every case to the same documented method.

The agency

Four capabilities, one case file.

Most agencies subcontract whatever falls outside their one skill. We keep field, digital and legal-support work under a single file so nothing is lost in the handover — which is where cases usually come apart.

What we investigate

Field Operations

Trained surveillance operatives running static and mobile observation, discreet enquiry and witness work across Assam and the Northeast, with multi-city relay coverage for subjects who travel.

Digital Forensics

Forensic imaging of devices, account intrusion tracing, open-source intelligence and cryptocurrency analysis — with evidence preserved in a form a cyber cell can act on.

Legal & Litigation Support

Reports formatted for the forum they are headed to, chain-of-custody logging, certification support for electronic records, and direct coordination with your advocate.

Correspondent Network

Vetted partner agencies across India and abroad, including members of the World Association of Detectives, briefed on the Indian evidentiary standard before they begin.

Hidden Door's lead investigator reviewing case documents in Guwahati, Assam

Our Lead Investigator

Founder · Guwahati, Assam

An IFS-certified private detective whose background sits across three fields that rarely appear in the same person: traditional field investigation, digital forensics and wildlife crime. That combination is why cases which would normally be split across three agencies can be run as one file here.

He directs the agency's field operatives, forensic analysts and correspondent partners, and reviews every report before it is issued.

Where we operate

Guwahati directly, every Indian state and union territory through resident associates, and internationally through vetted correspondent agencies.

Areas we serve

Mission & approach

Truth is not discovered. It is pursued.

No two cases are alike, so no two investigations should be. Every file starts with a strategy built for that file — and an honest account of what it can and cannot achieve.

We write down what we cannot establish

A report that only contains findings is a sales document. Ours state the gaps — the source that would not confirm, the record that no longer exists, the observation we could not lawfully make. Those gaps are frequently the most useful page in the file.

Method beats access

Investigators sell access: a contact, a database, a shortcut. Access is unreliable and often unlawful. What holds up is a repeatable method applied patiently — verify to source, log contemporaneously, keep observation separate from inference.

We turn down work

Requests to intercept communications, access accounts, or trace someone for a purpose we are not comfortable with are refused regardless of the fee attached or the story told at intake.

Accountable by design

Every engagement gets a named case officer who scopes it, reviews the evidence and signs the report — supported by field operatives, forensic analysts and correspondent agencies. You always know who is answerable for your file.

How a file runs

Our investigation method.

Step 01

Free Consultation

One conversation on an encrypted line, at no charge. We establish what you actually need to know — which is often not the question you arrived with — and whether it can be answered lawfully.

Step 02

Written Scope

What is in scope, what is deliberately out of it, what methods will be used, what it costs and what it cannot promise. You sign it before any money changes hands.

Step 03

Field Work

Documented as it happens, not reconstructed afterwards. Observation logs are contemporaneous, devices are imaged before examination, every document recorded with source and date.

Step 04

Report & Debrief

An executive summary you can act on, an evidence index your lawyer can work from, and an explicit statement of what could not be established. Delivered to named recipients only.

Boundaries

What we are — and what we are not.

Hidden Door is not a law enforcement agency. We hold no statutory powers of arrest, search, seizure or interception, and we do not claim proximity to anyone who does. We do not intercept communications, access accounts or devices without authority, impersonate public servants, trespass, or obtain records by deception — all of which are offences, and all of which produce evidence that collapses the moment it is examined.

What we do is lawful fact-finding, documented to a standard that survives challenge, and handed to the person who can act on it: you, your advocate, your board, or the appropriate authority.

Who will actually handle my case?
Our lead investigator scopes, reviews and signs every file. Field operatives and correspondent agencies support the work, but the person you speak to at intake is the person accountable for the report. We do not publish the names of our investigators — discretion protects our clients as much as it protects us.
Are you licensed?
India has no central licensing regime for private investigators. What we hold instead are professional certifications — IFS private detective certification, EC-Council and IIT Kanpur ethical hacking credentials, IHA body language certification and wildlife forensics training — plus membership of the Association of Private Detectives & Investigators and the World Association of Detectives.
What work do you refuse?
Anything requiring interception of communications, unauthorised access to accounts or devices, trespass, impersonation of a public servant, or obtaining records by deception. We also decline cases where the cost of the answer clearly exceeds its value to the client — that refusal comes at intake, not after a retainer.
Do you give legal advice?
No. We produce material your advocate uses; the strategy for using it is theirs. Where a matter needs a lawyer rather than an investigator, we say so.

Next step

Speak to the team that will handle your case.

Not a sales desk. The first conversation is with an investigator who can scope the work, tell you what it takes and say plainly whether we are the right agency for it.
