Managed IT Services San Diego
San Diego businesses don’t have a generic IT problem. A genomics startup in Sorrento Valley, a machine shop in Kearny Mesa feeding Navy contracts, and a medical group in La Mesa are all “SMBs” — but they answer to completely different regulators, face different attackers, and lose money in different ways when systems go down.
That’s why CyberDuo doesn’t sell a one-size IT plan with security bolted on top. We’re a cybersecurity company that delivers managed IT. Every client gets 24/7 threat detection from our security operations center, a helpdesk that answers in minutes, and a dedicated vCIO who actually knows your industry’s rules — whether that’s HIPAA, NIST 800-171, or an enterprise customer’s 200-question security review.
If your current provider’s idea of cybersecurity is antivirus and crossed fingers, you’re the reason ransomware crews like Southern California.

Why San Diego companies switch to CyberDuo
Usually it’s one of three triggers.
A close call. A wire nearly diverted, a phishing email an employee almost clicked, a competitor in the news for ransomware. The current IT vendor’s response — “we can quote you a security package” — makes it obvious security was never part of the plan. With us, it is the plan: managed detection and response, email security, MFA enforcement, vulnerability management, and staff training are in the base offering, not the upsell menu.
A compliance deadline. A prime contractor sends a CMMC flow-down letter. A new enterprise customer sends a security questionnaire that the current MSP can’t answer. An insurance renewal arrives with twenty new security requirements. We live in these frameworks daily — NIST 800-171, HIPAA, SOC 2, CCPA — and we hold our own SOC 2 Type II attestation, so we can show you our audit instead of describing one.
Slow support that’s gotten expensive.
Tickets that age for days. An “account manager” who changed three times this year. Onsite visits scheduled like cable appointments. Our average first response is 10 minutes around the clock, 85% of issues are fixed on the first call, and when hands-on work is needed in San Diego, an engineer is dispatched the same day.
If any of those sound familiar, the assessment is free and the report is yours to keep either way.
Certifications that matter (and why)
SOC 2 Type II Attestation
Your MSP has administrator access to everything you own — so their security is your security. We completed an independent, months-long Type II audit of how we actually operate. Most MSPs serving San Diego haven’t. It’s a fair first question to ask anyone bidding for your business — we’ll hand you ours under NDA.
CMMC / NIST 800-171 Ready Services
San Diego has one of the largest defense economies in the country — shipbuilding, unmanned systems, C4ISR, and thousands of small suppliers underneath the primes. If DoD work touches your revenue, CMMC determines whether you keep it. We build 800-171-aligned environments, write the SSP and POA&M with you, and get you assessment-ready.
CISSP-Led Security Practice
Our security program is designed and run by CISSP-certified professionals — the highest-recognized credential in the field — not by generalist technicians who took a vendor webinar.
Microsoft Solutions Partner | Azure Solutions Architect Expert | M365 Administrator Expert
Most of San Diego runs on Microsoft 365 and Azure. We harden tenants, manage identity and conditional access, optimize licensing spend, and run migrations without burning a workday.
San Diego industries we work with
Biotech & Life Sciences
Sorrento Valley / Torrey Pines / UTC
San Diego is one of the top three life-science clusters in the country, and the IT stakes match: research data and IP that foreign actors actively target, lab instruments that can’t just be rebooted mid-run, GxP environments where change control is non-negotiable, and pharma partners whose security teams will audit yours. We secure research environments, segment lab networks from office networks, and give scientific teams fast support that respects validated systems.
Software & Technology
Sorrento Valley / UTC / Downtown
San Diego’s tech scene is full of companies at the stage where enterprise deals start arriving with security questionnaires attached. We give growth-stage teams a security posture that passes customer due diligence — SSO, device management, audit logging, documented policies — without putting speed bumps in front of engineering.
Law Firms & Professional Services
Downtown / UTC / Carlsbad
Confidentiality is the product. Document management security, matter-level access control, protection against the wire-fraud schemes that target firms during transactions, and responsive support that works from the office, the courthouse, or home.
Defense Suppliers & Government Contractors
Countywide
Between the Navy’s massive footprint, NAVWAR, shipbuilders, and the unmanned-systems industry, an enormous share of San Diego’s manufacturing and engineering firms touch CUI — often without fully realizing what that obligates them to. This is our deepest specialty. We take suppliers from “we got a flow-down letter and we’re not sure what it means” to an operating NIST 800-171 environment with the documentation to prove it. For many clients, this work directly protected contract revenue.
Manufacturing & Craft Production
Kearny Mesa / Otay Mesa / Vista / Carlsbad
Precision shops, electronics, sporting goods, and the county’s famous brewing industry share one thing: when systems stop, production stops. We support shop-floor and OT environments most MSPs avoid, protect CAD and recipe / process IP, and design networks where one infected office laptop can’t reach a production line.
Hospitality & Tourism
Gaslamp / Mission Bay / Coronado
Hotels, restaurant groups, and attractions need PCI-compliant payment environments, guest Wi-Fi properly segmented from operations, and support coverage that matches an industry where the busiest hours are nights and weekends. Convenient, since our helpdesk doesn’t close.
Healthcare & Medical Practices
Scripps / Sharp / UCSD orbit & independent practices
Medical groups, surgery centers, behavioral health, and specialty clinics across the county run on EHRs that cannot go down and PHI that cannot leak. HIPAA-compliant infrastructure, encrypted and immutable backups, vendor (business associate) management, and phishing training that measurably cuts click rates — that’s the standard package, not the deluxe one.
Cross-Border Trade & Logistics
Otay Mesa / San Ysidro
Operating across the busiest land border crossing in the Western Hemisphere means customs systems, brokers, carriers, and partners on both sides — a wide attack surface for payment fraud and business email compromise. We lock down the email and payment-verification workflows where these losses actually happen.
Nonprofits
Countywide
Donor data deserves the same protection as customer data, on a budget that has other priorities. We right-size the stack using nonprofit licensing programs (including Microsoft’s grants) so security doesn’t compete with the mission.

Client Testimonials
Questions San Diego businesses should ask any MSP (including us)
Can I see your SOC 2 report?
Not their compliance services — their own audit. We’ll share ours under NDA. Watch how others answer.
Who exactly shows up onsite, and from where?
Plenty of providers “serve San Diego” from a dispatch queue two counties away. Ask for the local address and how same-day requests actually get handled. Ours is 402 W Broadway, Downtown San Diego.
What’s in the base price, and what’s an add-on?
If EDR, MDR, and email security are upsells, the base plan is insecure by design. Typical fully managed IT in San Diego runs $100–$250 per user per month depending on compliance load and environment complexity — we’ll give you an exact number after a free assessment.
What’s your measured response time?
Get a number with a definition, not “fast.” Ours: 10-minute average first response, 85% first-call resolution, 24/7.
Who do I actually talk to?
A named vCIO and a stable engineering pod — or a ticket queue and a rotating cast? You’ll feel the difference within a quarter.
Frequently Asked Questions
How much do managed IT services cost in San Diego?
Do you have a physical office in San Diego?
We're a defense supplier and just received a CMMC flow-down letter. Where do we start?
Can you support our lab or production environment, not just office computers?
We have one internal IT person. Do we have to replace them to work with you?
What happens if we're hit with ransomware right now?
How long does it take to switch from our current MSP?
Typically 2–4 weeks: discovery and documentation, security baseline deployment, helpdesk cutover, then a 30-day stabilization review. We run the transition as our project, including the awkward handoff conversations with your outgoing provider.
Do you support hybrid and remote teams?
Yes — secure remote access, conditional access policies, managed endpoints, and Microsoft 365 governance are standard. A large share of our client base has been hybrid for years.
Which San Diego areas do you cover onsite?
All of San Diego County — see the coverage table below. Remote-first for speed; same-day onsite when hands matter.

The free assessment that pays for itself
Tell us about your environment and we’ll benchmark it against your industry’s actual requirements — security posture, compliance gaps, and where your current IT spend is leaking. You get the findings either way. No 40-slide deck, no pressure, one flat price if you want us to fix what we find.
