Part of our nationwide cybersecurity incident response practice — see methodology, full service catalog, and pricing.
When an attacker gets into a San Jose company’s email, files or servers, the first hours decide how much it costs. Our incident response work is delivered remotely by U.S.-based engineers, so containment can start as soon as we have admin access, without waiting on a drive across Silicon Valley. Most of the cases we handle are compromised Microsoft 365 / Office 365 or Google Workspace accounts, business email compromise and ransomware, for organizations in venture-backed startups & saas, healthcare & medical practices, professional services & real estate and advanced manufacturing & clean tech. California’s breach notification statute, Cal. Civ. Code § 1798.82, sets the clock once personal information is exposed. We cover Downtown San Jose, North San Jose, Willow Glen, Santana Row, Santa Clara and Sunnyvale and the rest of the Silicon Valley area.
What We Offer
Comprehensive cybersecurity incident response tailored for San Jose businesses
Microsoft 365 / Office 365 Compromise
Hidden inbox rules, forwarding, OAuth app grants, attacker MFA methods and live sessions found and removed across the tenant.
Google Workspace Compromise
Gmail filters and forwarding, third-party app grants, outside Drive sharing and admin changes cleaned up, audit logs preserved.
Business Email Compromise
Bank recall support, scoping of what the attacker read and sent, and evidence for IC3 and your insurer.
Ransomware Containment
Isolate without destroying evidence, find the entry point, verify backups before restoring, rebuild clean.
Forensic Scoping
Audit, sign-in and endpoint logs preserved early to answer what data was accessed and whose.
Hardening After the Incident
Phishing-resistant MFA, conditional access and alerting in place before the case closes.
Industries We Serve
Specialized expertise for Silicon Valley's key industries.
Venture-Backed Startups & SaaS
For technology companies the worry after an account takeover is customer data and source code. We check cloud tenant and code repository access, revoke tokens and keys the attacker could reuse, and give you a clear account to share with customers who ask.
Healthcare & Medical Practices
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.
Professional Services & Real Estate
A spoofed or compromised email that changes wire instructions on a draw request or a closing is the incident we see most in construction and real estate. Speed matters for a bank recall, so we start there, then clean up the mailbox and the tenant.
Advanced Manufacturing & Clean Tech
In industrial environments, containment cannot mean pulling every plug. We isolate the business network from the control network first, confirm whether the attacker reached OT systems, and work with your operations team so safety and production decisions stay with the people who own them.
