Managed IT services for Sunnyvale businesses

Sunnyvale blends major technology employers around Moffett Park with a genuinely local main-street economy along Murphy Avenue and El Camino Real. The businesses we support here are typically professional services, healthcare, specialty trades and small product companies with ten to eighty employees. They share one trait: staff who are technically comfortable and therefore quick to notice when systems are slow, but who have no interest in maintaining infrastructure themselves.

For a Sunnyvale business, managed IT means your servers, laptops, firewalls, switches and cloud tenant are all monitored, patched, backed up and documented by one accountable team under a single flat monthly agreement — no hourly meter running while your staff waits.

Under the hood: automated patching, endpoint detection and response on every device, monitored local and cloud backups with documented restore testing, licensing right-sized against actual usage, and vendor management so you stop being the middleman between your ISP and your line-of-business software provider.

Leadership also gets the part most providers skip: quarterly technology reviews covering incident trends, hardware age, license spend, security posture and a rolling twelve-to-eighteen-month roadmap. Budgeting for Sunnyvale technology becomes planned rather than reactive.

  • 24/7 remote monitoring and alerting on Sunnyvale servers, workstations and network gear
  • Unlimited help desk by phone, email and remote session
  • Patch management for Windows, macOS and third-party applications
  • Managed EDR, MFA enforcement and ransomware protection on every endpoint
  • Monitored local + cloud backups with documented recovery testing
  • Quarterly technology reviews and budget planning with a real engineer

IT support and computer repair in Sunnyvale

Sunnyvale environments usually fail at the seams rather than the center. Core systems are fine; the trouble lives in the transitions — the VPN that drops for remote staff, the shared drive that never fully migrated to SharePoint, the second office added without redesigning the network, the backup that covers the server but not the laptops holding actual working files.

Our Sunnyvale support model is tiered: a fast first-response technician for the everyday tickets, escalation to network and server engineers for the complex ones, and a named account engineer who actually remembers how your environment is built.

Alongside business support we handle straight repair work for Sunnyvale residents and sole proprietors: virus and malware removal, data recovery from failing drives, SSD and memory upgrades, screen and battery replacement, Windows and macOS rebuilds, printer and peripheral setup, and secure data migration to a new machine.

  • Half-finished file server to SharePoint migrations leaving data in two places
  • Remote-access VPNs that drop or run painfully slow for hybrid staff
  • Laptop data excluded from backup because only the server is protected
  • Aging firewalls with expired security subscriptions still in production

Network installation, structured cabling and Wi-Fi in Sunnyvale

Many Sunnyvale suites were wired for a very different era of office density. We commonly find one data drop per office in buildings now hosting three times the intended headcount, plus daisy-chained unmanaged switches under desks. We replace that with proper CAT 6 runs to a labeled patch panel, PoE managed switching and access points sited from a heat map — usually in a single weekend cutover.

We design networks from a site survey rather than guesswork: CAT 6 and CAT 6A structured cabling terminated and labeled to standard, managed switches with VLAN segmentation separating staff, guest, payment and camera traffic, business-grade firewalls, and Wi-Fi 6 or Wi-Fi 6E access points positioned from measured coverage instead of a floor-plan estimate.

We are a Cisco Meraki and Ubiquiti shop for good reason — both give Sunnyvale clients cloud-managed visibility, so a configuration change or a diagnosis does not require someone standing in your server closet. Firewall deployment, site-to-site VPN between Sunnyvale and your other offices, VoIP phone systems and IP security cameras are all part of the same design conversation.

  • CAT 6 / CAT 6A structured cabling for Sunnyvale offices, warehouses, clinics and homes
  • Managed switches, VLAN segmentation and PoE for cameras and phones
  • Wi-Fi 6 / 6E site surveys, access point installation and heat mapping
  • Cisco Meraki and Ubiquiti UniFi design, deployment and support
  • Firewall installation, site-to-site VPN and multi-location networking
  • Server racks, patch panels, VoIP handsets and full as-built documentation

Microsoft 365, cloud, servers and cybersecurity for Sunnyvale

Nearly every Sunnyvale business we meet already runs Microsoft 365 or Google Workspace, usually configured years ago by whoever was available and rarely secured since. We take ownership of the tenant: licensing right-sized to real usage, SharePoint and Teams structured so files are findable, retention and legal hold configured, and a documented security baseline applied.

Email migration is one of our most-requested projects locally: moving Sunnyvale teams off legacy POP/IMAP hosting, Google Workspace, or an on-premises Exchange server into Microsoft 365 over a weekend, with mail, calendars, contacts and shared mailboxes intact and no lost messages.

On the security side, attackers do not skip Sunnyvale — small and mid-sized employers are targeted precisely because their defenses are assumed to be thinner. The incidents we respond to most are business email compromise, credential theft through convincing Microsoft 365 phishing pages, and ransomware that walked in through an unpatched workstation. We answer with layers: MFA and conditional access, managed EDR that can isolate an infected device automatically, DNS and email filtering, phishing simulation training, dark-web credential monitoring, and immutable backups that survive an attacker with domain admin.

Backup and disaster recovery is the piece everyone postpones. We deploy layered protection — a local appliance or NAS for fast restores plus encrypted offsite replication for a site-loss scenario — then test restores on a schedule so your Sunnyvale team knows recovery works before the day it matters.

  • Microsoft 365 and Google Workspace administration, licensing and security baselines
  • Email migration to Microsoft 365 with zero lost mail
  • Windows Server installation, migration, Active Directory and file services
  • NAS storage, backup appliances and encrypted offsite replication
  • Documented disaster recovery plans with tested restore runbooks
  • Endpoint protection, MFA, email security and security awareness training

Residential IT, smart home networking and computer repair in Sunnyvale

Sunnyvale homes in Cherry Chase, Ponderosa Park and Lakewood are frequently older builds with detached garages, ADUs and home offices well outside router range. We run wired backhaul, install outdoor-rated access points where needed, and set up secure remote-work environments that hold up on video calls all day.

Typical residential visits in Sunnyvale include whole-home mesh Wi-Fi design for houses where the router sits in the wrong corner, running CAT 6 to offices, media rooms and outdoor access points, setting up secure remote-work environments, installing and configuring security cameras and doorbells, separating smart-home devices onto their own network, and cleaning up computers that have slowed to a crawl.

We also handle the household projects nobody enjoys: migrating a decade of photos to a new laptop, recovering data from a failing drive, setting up NAS storage and automated backups, tuning networks for gaming and 4K streaming, and installing parental controls that actually hold up.

  • Whole-home Wi-Fi design, mesh installation and dead-zone fixes in Sunnyvale
  • CAT 6 wiring for home offices, media rooms and outdoor access points
  • Virus and malware removal, tune-ups, SSD upgrades and data recovery
  • Security camera and video doorbell installation with secure remote viewing
  • Smart-home network segmentation, NAS storage and automated backups

Frequently asked questions

Can you finish a stalled Microsoft 365 migration for our Sunnyvale office?
Yes, and it is a frequent request. We audit what actually moved, resolve permission and sync conflicts, complete the remaining data migration, retire the old file server safely and train staff on the final structure.
Do you support ADU or detached home offices in Sunnyvale?
We do. Detached spaces usually need wired backhaul or a properly aimed outdoor access point rather than another mesh node — we design for the actual distance and building materials.
How quickly can you respond on site in Sunnyvale?
On-site visits are scheduled, typically same week and often next day for managed clients. Critical issues get a 15-minute remote response, and the majority of tickets are solved remotely before a visit is needed.
Do you offer after-hours cutovers in Sunnyvale?
Yes. Cabling, server migrations, firewall replacements and network cutovers are scheduled evenings or weekends so your Sunnyvale team starts Monday on a finished system.
Do you offer emergency IT support in Sunnyvale?
Yes. Managed clients have 24/7 emergency escalation for outages, ransomware and security incidents, with a 15-minute response target on critical tickets. Non-contract emergency work is quoted before we start.
How much does IT support in Sunnyvale cost?
Managed agreements are priced flat per user per month and cover monitoring, help desk, patching, endpoint security and backups. Project work — cabling, server installs, migrations — is quoted fixed-price after a site walkthrough. Call (209) 517-6976 for a same-week quote.
