What Attacks on Bay Area Businesses Actually Look Like

Forget the hoodie-in-a-basement image. The attacks hitting San Francisco companies are businesslike: a fake wire-change email that mirrors your title company’s writing style during a real closing. A counterfeit DocuSign notice sent to a law firm the week a deal signs. An MFA-fatigue push storm against a fintech engineer at 11 PM. A vendor invoice, perfectly formatted, from a supplier whose mailbox was quietly compromised months ago.

Three things make this city a target-rich environment. First, the money is visible — funding rounds are announced, deal news is public, and attackers read the tech press too. Second, the workforce is hybrid and cloud-native, so the security perimeter is every laptop on every home network from the Sunset to Sausalito. Third, the data is dense: a mid-size firm in the Financial District or Mission Bay may hold source code, customer PII, and investor documents that would each be a payday alone.

  • MFA and conditional access on every entry point
  • Departures offboarded same-day, access reviewed quarterly
  • Immutable, tested backups that make ransom demands pointless
  • 24/7 detection — dwell time in minutes, not months

The Security Stack We Run

Layered Defense, Managed Around the Clock

Every layer monitored by our operations team — because unwatched security tooling is just expensive logging.

Endpoint Detection & Response
EDR on every Mac and PC — office, home, or airport — with managed response when something detonates, not a Monday-morning alert review.
Email & Identity Protection
Phishing filtration, domain spoof protection, MFA enforcement, and conditional access — closing the door attackers try first.
SIEM & Dark-Web Monitoring
Logs correlated across your environment, with alerts when employee credentials surface in breach dumps or criminal markets.
Phishing Training That Sticks
Simulations modeled on campaigns hitting Bay Area firms — wire fraud, fake DocuSign, vendor impersonation — with coaching, not shaming.
Incident Response
A written, rehearsed playbook: isolate, investigate, restore from tested backups, notify correctly. Hours matter; so does order of operations.
Compliance & Evidence
Controls documented for SOC 2, HIPAA, PCI, and insurance applications — evidence as a byproduct, not a scramble.

San Francisco Cybersecurity FAQ

What SF founders, partners, and office managers actually ask us.

We’re a 30-person company. Are we really a target?
Small SF firms are targeted more, not less — attackers assume enterprise-grade data behind small-business defenses, and they’re usually right. Wire fraud and vendor-email compromise hit 20-to-100-person Bay Area companies every week.
Doesn’t Microsoft 365 or Google Workspace security cover us?
Platform defaults stop commodity spam, not targeted attacks. They don’t cover endpoints, credential reuse, third-party SaaS, or response when something gets through. We harden the platform and add the missing layers — see our Microsoft 365 services for San Francisco.
What does a security incident actually cost a firm like ours?
Wire-fraud losses are routinely six figures; add breach counsel, forensics billed hourly, deals paused during due diligence, and a cyber-insurance premium jump at renewal. Prevention is reliably the cheapest line item on the list.
Can you get us through a cyber-insurance application?
Yes — we implement the controls carriers now require (MFA, EDR, tested backups, offboarding discipline) and produce the evidence they ask for. See our cyber insurance readiness service.
An enterprise customer sent a 200-question security questionnaire. Help?
Routine for us. We maintain your control documentation so questionnaires are answered from evidence in days, not invented in a panicked all-hands. For formal attestation, we run SOC 2 preparation for San Francisco companies.
Do you replace our IT provider or work alongside them?
Either. We run security standalone next to an incumbent IT firm or internal team, or as one layer of our complete San Francisco managed IT services.
