Industry-Specific IT Expertise in Chicagoland

Trading, Asset Management & Banking: Financial firms are a favorite target for business email compromise because a single altered wire instruction pays well. We move fast on bank recall, find every forwarding rule and OAuth grant the attacker planted, and preserve the evidence your regulator or carrier will ask for. Under the FTC Safeguards Rule, covered firms must also report qualifying incidents to the FTC.

We design IT solutions that address these requirements from day one, rather than retrofitting generic technology to fit industry-specific needs.

Healthcare Practices & Health Tech: A compromised mailbox at a practice is rarely just an email problem, because referral letters, lab results and insurance forms sit in it. We scope exactly which messages the attacker could read so your privacy officer can run the HIPAA breach risk assessment on facts instead of assumptions.

For Chicago businesses, incident response is delivered remotely by U.S.-based engineers, which is why it can start as soon as we have admin access rather than when a technician arrives. In a compromised Microsoft 365 or Google Workspace tenant we revoke sessions and tokens, remove attacker MFA methods, inbox rules, forwarding and app grants, preserve the audit logs, and scope what data was read or sent. For ransomware we isolate affected machines without destroying evidence, verify backups before restoring and rebuild from known-good images. Where hands-on work is needed, we coordinate it as part of the response.
