Microsoft 365 exposure assessment
Find the Microsoft 365 signals attackers use first.
ExposureSignal reviews externally observable Microsoft 365, identity, email, and domain conditions, then connects priority gaps to practical remediation and business impact.
What you gain
See the identity and email perimeter from the outside.
The signal blends asset exposure, credential pressure, control gaps, and projected loss into one operating picture for security and leadership.
Review public sign-in pathways, legacy exposure indicators, privileged role context, and identity-related attack opportunities.
Assess SPF, DKIM, DMARC, mail routing, and domain conditions that influence spoofing and impersonation risk.
Map tenant-connected domains, subdomains, certificates, and services that widen the Microsoft 365 attack surface.
How it works
Connect public Microsoft 365 signals to a focused plan.
Map tenant-facing domains
Identify domains, mail records, authentication records, and public services connected to the organization.
Review identity exposure
Examine observable access pathways and the conditions that increase account takeover or password attack risk.
Assess email trust controls
Validate whether domain authentication and mail configuration reduce spoofing and impersonation opportunities.
Prioritize remediation
Organize high-impact identity, email, and domain actions into an owner-ready sequence with validation steps.
From evidence to action
Reduce identity and impersonation exposure.
The assessment focuses on externally observable conditions. Internal tenant configuration and licensing may require separately authorized review.
Strengthen public identity pathways
Reduce exposure to password attacks and account takeover by addressing reachable legacy or weak access conditions.
Improve domain authentication
Use correctly aligned SPF, DKIM, and DMARC controls to reduce unauthorized use of organizational domains.
Monitor tenant-related footprint change
Catch new domains, services, records, and certificate events that alter the external Microsoft 365 exposure picture.
Start with a clear signal
Turn your external footprint into a prioritized response plan.
See your current external exposure, the findings that deserve attention first, and the evidence your team can use to act.
