Authentication Posture
SPF, DKIM and DMARC across every sending domain and subdomain - is DMARC actually at enforcement, and is each source aligned?
Email Security Audit · India-based, serving worldwide
Audit Your Email Attack Surface - Before Someone Else Does
A one-time, fixed-fee audit of everything an attacker could use against your email: authentication gaps, spoofability, lookalike domains, gateway and reputation. You get a graded, cyber-insurance-ready report and a prioritised fix plan - the same checks we run at the start of every client engagement, packaged as a standalone audit.

What the Audit Covers
Six inspection areas across every domain you own - the full picture of how attackable your email really is.
🛡️
Spoofability & BEC Exposure
The core test: can an outsider send email as your domain today? We run the inbound battery and translate each gap into a real attack scenario.
🎭
Domain & Brand Impersonation
Lookalike and cousin domains an attacker would register, plus your own parked or unprotected domains that can be spoofed.
🔗
Transport & Gateway
MX and gateway configuration, MTA-STS and TLS-RPT posture, and open-relay or misconfiguration checks.
📈
Reputation & Hygiene
Blacklist standing of your domains and sending IPs, plus DMARC evidence of every source really sending as you - including shadow IT.
📋
Prioritised Remediation Plan
Every finding rated Critical to Low, with concrete fixes in priority order - not a data dump, a to-do list.
The Questions Clients Ask First
"Why not just use your free tools?"
The free Spoof Check tells you a problem exists. The audit tells you how bad, across every domain you own, with real attack scenarios and a fix plan you can hand to your team or ours.
"We already passed a security audit."
Most general security audits barely touch email - yet business email compromise is among the costliest cyber claims and lives entirely in email. This is the email-specific audit those reviews skip.
"Do insurers really ask for this?"
Yes. Cyber-insurance questionnaires and compliance reviews ask whether you assess and test your email security. A dated, branded, third-party report is exactly the evidence that answers it.
How the Audit Runs
1
Scope & Discovery
A short questionnaire to map every domain you own and every service that sends as you - you cannot assess what is not enumerated.
2
Run the Battery
Authentication, spoofability, lookalikes, gateway and reputation - largely from public DNS plus our own tooling, so it is fast and non-intrusive.
3
Evidence Window
A short DMARC monitoring window (where you allow it) shows, in plain English, every source really sending as your domain.
4
Report & Readout
A graded PDF with findings, attack scenarios and a prioritised plan, walked through on a call.

Email Security Audit - Frequently Asked Questions
What is in the report?
An executive summary with an overall grade, findings by domain rated Critical to Low, two or three concrete attack scenarios drawn from your actual gaps, a prioritised remediation plan, and an evidence appendix.
How long does an email security audit take?
Usually one to two weeks, including a short DMARC evidence window. Urgent situations (an active incident or an insurance deadline) are prioritised.
Is it a one-time fixed fee?
Yes. It is a one-time, fixed-fee engagement scoped to the number of domains you own - no hourly surprises.
Will it satisfy our cyber-insurance questionnaire?
It is designed to. The report is a dated, branded, third-party audit that answers the "do you assess and test your email security?" line on insurance and compliance questionnaires.
How is this different from a deliverability audit?
Same underlying muscle, a security lens: spoofability, BEC exposure, impersonation and the insurance-ready framing, rather than inbox-placement optimisation.
Who can help with an email security audit, and do you work in India?
Postbox Consultancy Services is an India-based email deliverability and security consultancy. We run audits for businesses in India and worldwide.
