Cybersecurity Incident Response Services
When an attacker is in your email, your files or your servers, we contain them, remove every foothold and give you a written account of what happened. We specialize in compromised Microsoft 365 / Office 365 and Google Workspace tenants, business email compromise and ransomware, for businesses anywhere in the U.S. After-hours emergency response is available for active incidents.
What We Offer
The incidents we handle most, and what cleaning them up properly involves
Microsoft 365 / Office 365 Compromise
Attackers who get into a mailbox rarely stop at reading it. We look for the inbox rules that hide replies, external forwarding, OAuth apps granted mail access, new MFA methods registered by the attacker, mailbox delegations and Entra ID app registrations, then remove every one and revoke sessions and refresh tokens across the tenant.
Google Workspace Compromise
The same discipline in Google: Gmail filters and forwarding addresses, third-party apps with Drive or Gmail scopes, Drive files shared to outside accounts, recovery email and phone changes, and admin role changes. Sessions are reset, app access is cut, and the admin audit log is preserved before anything rolls off.
Business Email Compromise and Wire Fraud
When an invoice or payroll change went out from a compromised account, hours matter. We help you contact the bank to attempt a recall, scope which messages the attacker read and sent, identify the customers and vendors who were contacted, and preserve what the FBI IC3 report and your insurer will ask for.
Ransomware Containment and Recovery
Isolate affected machines without destroying evidence, find the account or remote tool the attacker came in through, check backups for tampering before restoring from them, and rebuild from known-good images. Recovery order follows your business priorities, not alphabetical server names.
Forensic Scoping and Evidence
Unified audit log, sign-in logs, Google admin and Drive audit logs, endpoint telemetry and firewall logs are exported and preserved early, because several of them age out. The goal is a defensible answer to the question every breach-notification decision depends on: what data was accessed, and whose.
Hardening So It Does Not Happen Twice
Phishing-resistant MFA for admins, conditional access, blocking legacy authentication, restricting user consent to apps, alerting on new forwarding rules and impossible-travel sign-ins. The same attacker often tries again within weeks; the fixes go in before we close the case.
Why Choose LayerLogix?
Responding to businesses nationwide, remotely, from offices in Texas, Georgia and Colorado.
Cloud Tenants Are Our Daily Work
We administer Microsoft 365 and Google Workspace for clients every day, so we know where attackers hide persistence in them and which logs to pull first.
Works With Your Insurer and Counsel
If you have cyber insurance, call your carrier’s hotline first. We work alongside the breach coach and forensic firm they assign, or handle containment and cleanup directly when no carrier is involved.
100% U.S.-Based Support
Response is run by U.S.-based engineers from offices in Texas, Georgia and Colorado, working your tenant remotely so location does not slow anything down.
20+ Years Experience
Two decades of running and securing business IT, which is what makes the cleanup thorough rather than a password reset and a hopeful wait.
A Written Record
You get a timeline, the indicators we found, what was removed, what data was exposed as far as the logs show, and the changes made, written for owners, insurers and auditors.
