A 12-person law office, a four-partner CPA firm, an architecture studio, a regional insurance agency, a nonprofit foundation. Different revenue, same IT pressure: a flood of phishing every week, a Microsoft 365 tenant nobody has hardened, a cyber-insurance renewal that just added thirty questions, and a partner who is leaving on Friday and still has full access to every client file on Monday. Ghosxt runs the IT, cybersecurity, and Microsoft 365 environment for professional offices across the Central Coast and the Bay Area: federal-grade engineering, transparent pricing, no outsourced helpdesk.
Rated 5.0 across 26 Google reviews, trusted by businesses across Monterey County since 2021 and beyond.

Professional office IT is its own discipline. There is no shop floor, no fleet, no cooler. The product is judgment, advice, and trust, and the threat surface is mostly the inbox. Below is the actual work, written for managing partners and office managers, not for procurement decks.
24/7 monitoring, helpdesk, patching, and a real engineer who answers the phone when an associate cannot get into the document management system at 8am on filing day. Coverage shaped around your billable hours, not nine-to-five tickets.
Learn moreDMARC, SPF, DKIM configured properly. MFA on every mailbox. Conditional access policies that block legacy auth. Real-time detection for inbox-rule abuse. AP and trust-account confirmation flows redesigned so a wire instruction cannot land without an out-of-band phone call.
Learn moreThe security baselines a default M365 tenant ships with off or wide-open: mailbox audit logging, retention, DLP, external sharing controls, app consent governance, conditional access. We turn them on, configure them for how your office actually works, and document what we changed.
Learn moreMatter- or client-level folder structures, explicit access lists, retention policies aligned to your professional rules, audit logging, default-deny posture on external sharing. The IT side of the duty of confidentiality, made operational.
Learn moreCCPA, GLBA, ABA Model Rule 1.6, state bar tech competence, SOC 2 readiness, cyber-insurance underwriting. We translate the requirement into a control, deploy the control, and produce the artifact your auditor, regulator, or carrier expects.
Learn moreSSO, conditional access by device and location, secure remote access without a single corporate VPN, and a tested setup for the partner who works two days a week from a vacation home in Carmel. Built on identity, not on routing tricks.
Learn moreProfessional service offices are not regulated by an industrial framework, but they carry a stack of legal, fiduciary, and ethical obligations that have IT teeth. Five that we see almost every week.
If you sit in California and you collect personal information about California residents (and you do, that is what client intake forms are), the California Consumer Privacy Act and Privacy Rights Act apply at the right thresholds. The IT side is access controls, breach detection, the ability to honor deletion requests, vendor agreements, and a documented retention policy that survives an attorney general inquiry.
The Gramm-Leach-Bliley Act and the FTC Safeguards Rule apply to a wider set of financial-data handlers than most owners realize. Small CPA firms, tax preparers, mortgage brokers, financial advisors. The current rules require designated security responsibility, risk assessments, MFA, encryption, vendor oversight, training, and an incident response plan. We deploy the controls and produce the program documentation.
Lawyers carry an explicit duty of confidentiality. California, like most states, has formalized that competence extends to the technology that holds client data. The IT side is encryption at rest and in transit, access controls scoped to matter, training that documents tech-competence compliance, secure document exchange with opposing counsel, and a documented incident-response plan that meets the bar's expectations.
If you sell into a larger enterprise as a consultant, agency, or technology provider, a SOC 2 attestation is becoming a procurement gate. Type 1 is the snapshot; Type 2 is the operating-over-time evidence. We get the controls in place, the policies written, and the evidence captured well before the assessor's window starts, so the audit becomes a one-week event instead of a six-month rebuild.
Not a regulation, but the practical compliance program every small office now runs whether they meant to or not. Modern carrier questionnaires ask about MFA coverage, managed detection and response deployment, backup resilience, mean time to patch, incident response, vendor risk, privileged access, and dark-web exposure. We answer with a real number and a real artifact, and we close the gaps before the renewal window opens.
A federal-grade engineering background brings the documentation and audit discipline these obligations actually require. The same controls that satisfy a federal contracting auditor satisfy a CCPA inquiry, a GLBA examination, a SOC 2 assessor, and a cyber-insurance underwriter, with the paper trail intact.
Four anonymized examples from real client work at Central Coast and South Bay offices. Names, locations, and matter specifics are removed; the patterns are what we see every month.
A small CPA firm's controller received a Friday-afternoon email that looked like it came from a longtime client requesting a same-day wire to a new account. The detection layer we had deployed flagged the message as a lookalike domain at the gateway and quarantined it before the controller saw it. The follow-up forensics found that the client's mailbox had been compromised the previous week and the attacker was waiting for a Friday afternoon. We helped the client remediate their tenant and the wire never went out.
A tax practice with eight staff was hit by a coordinated phishing campaign on the first Saturday in April. Two staffers clicked. We were paged inside an hour, isolated the affected accounts, audited mailbox forwarding and OAuth grants, and ran a full credential rotation. Nothing was exfiltrated. The post-incident work was the more useful part: we enabled token protection, tightened conditional access against unfamiliar locations, deployed a phishing-simulation training cadence, and locked down the M365 audit logging the firm needed to prove to the IRS that client data was not exposed.
A mid-size law office discovered, weeks after an associate left, that the associate had synced a large document set to a personal OneDrive account in the days before their departure. We rebuilt the offboarding lifecycle around a real procedure (revoke at the SSO and conditional-access layer in the same minute that payroll exit is logged, sync-block personal accounts in advance for departing staff, retain mailbox on hold, audit recent file activity, escalate findings to managing partner). The firm could not undo what happened, but it could prove a defensible response and ensure it does not happen the next time.
A two-office insurance brokerage's site-to-site VPN dropped on a Friday afternoon, the day a state filing was due. The secondary office had been working off shared file paths reachable only through that VPN. We rerouted critical access through identity (M365 / SharePoint with conditional access) while we rebuilt the tunnel. The filing went out on time. The architecture review afterward redesigned both offices to be identity-first: nothing critical hangs off a single VPN tunnel anymore, and a future ISP outage at either office is now a thirty-second failover instead of a four-hour scramble.
