Managed IT Services for Small and Medium Business Offices

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. DoD-cleared engineering, transparent pricing, no outsourced helpdesk.

Rated 5.0 across 24 Google reviews — trusted by 30+ businesses from Silicon Valley to the Salinas Valley and beyond.

What we do for SMB offices and professional service firms

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.

Managed IT for client-facing offices

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.

Email security and BEC defense

DMARC, 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.

Microsoft 365 hardening

The 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 more

Client confidentiality and document security

Matter- 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.

Compliance and cyber-insurance support

CCPA, 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 more

Multi-office and hybrid-work connectivity

SSO, 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.

Compliance frameworks we help SMB offices operate inside

Professional 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.

CCPA and CPRA for California offices

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.

GLBA for CPAs, financial advisors, and mortgage

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.

ABA Model Rule 1.6 and state bar tech competence

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.

SOC 2 readiness for consultancies serving enterprise

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.

Cyber-insurance underwriting baseline

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, EDR deployment, backup immutability, 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 DoD-cleared 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.

Common IT problems we see at SMB offices

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.

BEC wire-fraud near-miss

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.

Phishing wave during tax season

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.

Departing associate took a copy of the matter file

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.

Filing deadline VPN outage

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.

"Ghosxt has been our IT for years and the relationship just works. When we have a question, we get an answer fast. When something goes wrong, Ulises is on it before we have a chance to worry. The cybersecurity side has matured the office in a real way; our clients have noticed."

SMB office IT glossary

If you have run an office for any length of time, none of these are new. If you are the office manager or the partner who handles vendor decisions, this is the short version.

BEC
Business Email Compromise. The umbrella term for attacks where a real or lookalike email is used to redirect a payment or trick a target into releasing data.
MFA
Multi-Factor Authentication. Adding a second proof of identity (an authenticator app, a hardware key, a text code) on top of a password.
Conditional access
Identity policy that decides whether to allow a sign-in based on user, device, location, and risk. The control that turns "MFA on" into "MFA on, in the right way."
DMARC / SPF / DKIM
The three email-authentication standards that, together, let receiving mail servers tell a real message from your domain apart from a forgery.
EDR
Endpoint Detection and Response. The modern descendant of antivirus. Watches behavior on workstations and servers, not just file signatures.
DLP
Data Loss Prevention. Policies that detect and block sensitive information (SSNs, account numbers, regulated data) leaving the company by email or upload.
SSO
Single Sign-On. Letting people log in to many systems with one identity, governed by one set of policies. Foundation for everything else.
CCPA / CPRA
California Consumer Privacy Act, as amended by the California Privacy Rights Act. California's primary consumer privacy regulation.
GLBA
Gramm-Leach-Bliley Act. U.S. financial privacy law and the FTC Safeguards Rule. Applies to CPAs, tax preparers, financial advisors, mortgage brokers, and a long list of related fields.
SOC 2
An AICPA attestation standard increasingly required of consultancies and service providers selling into enterprise. Type 1 is point-in-time; Type 2 is over-time.

FAQs about IT services for SMB offices

We almost got hit with a wire-fraud email. Can you prevent this from happening again?
Yes. Business Email Compromise is the most common attack we respond to at small offices, and the playbook is consistent. We harden the mailbox layer (MFA everywhere, conditional access, modern auth only), we deploy real-time detection for new inbox forwarding and reply-to rules, we configure DMARC, SPF, and DKIM properly so lookalike domains are easier to block, and we rewrite the AP or trust-account confirmation process so a wire instruction cannot land without an out-of-band phone call to a known number. The combination is what stops repeat attempts.
We use Microsoft 365 and it works "fine." Do we still need help?
A default Microsoft 365 tenant is not secure. The security baselines that matter (modern auth only, conditional access, mailbox audit logging, retention, data loss prevention, external sharing controls, app consent governance) are off or wide open by default and the average tenant we walk into has not touched them. The mail works; that is not the same as the tenant being safe. Hardening a tenant is a one-time project that pays for itself the first time it stops an account takeover.
We have 12 people across two offices. How do we share files securely?
For most small offices, a properly governed SharePoint and OneDrive footprint beats a network file share or a generic cloud-storage account. The wins are at the governance layer: matter or client folder structures with explicit access lists, retention rules that match your professional standards, audit logging, and a default-deny posture on external sharing. Multi-office connectivity is handled at the identity layer (single sign-on, conditional access by location and device) rather than by routing all traffic through a single corporate VPN.
Our cyber-insurance renewal added 30 questions. Can you help us answer them?
Yes. Cyber-insurance underwriting has gotten sharper across every carrier and the questionnaire is now the cheapest way for them to set your rate. We answer the technical sections (MFA coverage, EDR deployment, backup immutability, mean time to patch, incident response plan, vendor risk management, privileged access) with a real number rather than a checkbox, and we close the gaps in advance so the renewal lands at the rate you want.
A partner is leaving and we need to lock them out fast. What does that look like?
Same-day offboarding done right is a fifteen-minute procedure if the systems are set up for it. We script the revocations: email and SSO disabled at a specific time, MFA tokens revoked, VPN and conditional-access exceptions removed, mailbox forwarded to a designated partner for client continuity, mailbox put on legal hold for the retention window, and any matter-system access logged for the audit. If you do not have those scripts ready when a partner walks out, the right time to build them is before the next one does.
