Cybersecurity Services in Bellevue, WA
Bellevue firms work next door to the companies attackers study most: T-Mobile, Amazon's Eastside offices, the game studios and cloud software firms downtown. NetSys protects the smaller businesses around them, whether that is a twelve-person accounting practice in a Bellevue Way tower or a studio in the Spring District, with managed detection and response, identity controls and email security.
The short answer
NetSys provides cybersecurity services for Bellevue businesses: ThreatDown managed detection and response on every laptop and server, Microsoft Defender for Business, multifactor sign-in enforced through Entra ID Conditional Access, Barracuda email protection, KnowBe4 phishing training, Keeper password management, Rapid7 vulnerability scanning and immutable backups. It is a remote service: NetSys does not send engineers on site in Bellevue. Alerts are worked 24/7 by monitoring and emergency staff, and the help desk is staffed from 1 a.m. to 8 p.m. Pacific. A common first step is the free external penetration test, a remote test of your internet-facing systems inside a scope we agree in writing.

How cybersecurity is delivered for Bellevue offices
Protection is run entirely from Brooklyn through consoles that reach each device and account wherever it is. ThreatDown watches every endpoint and escalates suspicious behavior to an engineer, who can cut a compromised laptop off the network in a single command, whether it sits in a Downtown Bellevue tower or on a kitchen table in Sammamish. Conditional Access policies, mailbox rules and admin roles are changed in Entra ID and Microsoft 365, not at a desk. NetSys does not send anyone to Bellevue offices. If a firewall needs replacing, the new one ships with its rules loaded and your staff plug it in. During an incident, your dedicated engineer leads the response by phone and Teams and documents each step for your insurer and counsel. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time (1 a.m. to 8 p.m. Pacific), seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work.
Identity attacks after the T-Mobile breaches
T-Mobile runs its headquarters out of Bellevue, and its 2021 breach exposed data on about 76.6 million current, former and prospective customers, leading to a $350 million class settlement that received final approval in June 2023. Data from breaches like that circulates for years and feeds the attacks that hit small firms: SIM swaps, password-reset calls to a help desk and phishing that already knows a target's address and phone number. That is why text-message codes are the weakest option we allow. We move staff to the Microsoft Authenticator app with number matching, or to hardware security keys for executives and finance, put a port-out PIN on company phone lines, and require our own help desk to call back on a number already on file before resetting a password or a second factor.
What Bellevue's software firms, studios and property managers need protected
Bellevue's economic development office has counted more than 45 corporate headquarters in the city, including Valve and Bungie, and the information technology sector is its largest employer. Software companies keep their value in code repositories and cloud consoles, so we separate admin accounts from daily accounts and require compliant devices before anyone reaches source code. Studios move huge asset files between workstations and build servers; those machines get endpoint protection tuned so it does not stall a build. Real estate developers and property managers are favorite targets for payment fraud, so a changed wire instruction triggers a verification call rather than a transfer. Medical practices near Overlake Medical Center need HIPAA audit logging and encrypted laptops. Each group gets the same core stack with different policies on top.
Washington rules that shape a Bellevue security program
Two Washington laws drive most of the paperwork. RCW 19.255.010 requires notice to affected residents in the most expedient time possible and no more than 30 calendar days after a breach is discovered; when more than 500 Washington residents are affected, the Attorney General must receive notice within 30 days, including the number affected, the data types, the exposure dates and the containment steps. The My Health My Data Act, in force for most regulated entities since March 31, 2024 and for small businesses since June 30, 2024, covers consumer health data outside HIPAA, requires consent before collecting or sharing it and gives consumers deletion rights that reach archives and backups. Violations count as Consumer Protection Act violations, enforced by the Attorney General and through private suits. This is general information, not legal advice.
The first 30 days of a Bellevue security engagement
We start from the outside. In week one the free external penetration test and a Rapid7 scan show what an attacker can reach from the internet, and an engineer reviews your Microsoft 365 tenant: who holds admin rights, which accounts lack multifactor sign-in and which mailboxes forward mail outside the company. Week two produces written findings ranked by risk, with a price for each fix. In weeks three and four ThreatDown replaces the old antivirus, number-matching multifactor sign-in rolls out by department, SPF, DKIM and DMARC are set to reduce spoofing of your domain, Keeper replaces spreadsheets of passwords and KnowBe4 sends a baseline phishing test. From day 30 you get a monthly report on alerts handled, patches applied and accounts that need attention.
Cybersecurity in Bellevue, Washington: what NetSys delivers
Watch and respond

Law office: layered security on Microsoft 365 with cloud-to-cloud backup
A 25-attorney firm needed client confidences protected better than a closet server could manage. Alongside a Microsoft 365 migration, NetSys layered anti-phishing and email threat protection, DNS filtering, multifactor authentication on every account and endpoint protection across attorney devices in the office and remote, and established independent cloud-to-cloud backup of the entire tenant because the recycle bin is not a backup strategy for privileged material. The firm reported 82% fewer IT support incidents per month within two quarters.

What cybersecurity costs in Bellevue, Washington
Cybersecurity is priced per user per month when it runs as an ongoing service, and per project for an assessment or a remediation. What moves the number: how many devices and identities are in scope, how much incident remediation and recovery is needed beyond the monitoring and authorized MDR actions in scope, which compliance standard the evidence has to satisfy, and whether the Microsoft 365 tenant is already on Business Premium or the security tooling comes from us. The free external penetration test costs nothing and runs remotely before any of that. Our managed IT pricing page explains how the fee is built.
Who this fits, and who it does not
Best fit: businesses with enough people, money movement or regulated data that a breach would hurt, and no security team of their own: professional practices, healthcare groups, importers, financial firms, nonprofits and agencies holding client credentials. Companies with an internal IT person fit as a co-managed arrangement.

Cybersecurity in Bellevue, Washington: FAQs
How does cybersecurity work for Bellevue organizations?
It runs remotely from start to finish. Agents on your laptops and servers report to ThreatDown and NinjaOne, identity and email controls live in Microsoft 365 and Entra ID, and firewalls are managed through Meraki or Fortinet cloud dashboards. NetSys does not send engineers to Bellevue; if equipment needs replacing it ships preconfigured. Monitoring and emergency service run around the clock, the staffed help desk covers 1 a.m. to 8 p.m. Pacific, and a ransomware alert at midnight goes straight to your dedicated engineer.
How much do cybersecurity services cost in Bellevue, WA?
We price security per user per month after assessing your environment, and we do not publish a rate. Inside a managed IT agreement, the core controls are already included. As a standalone service, the figure depends on the number of users and devices, servers and cloud workloads to watch, whether you need compliance evidence for HIPAA, the My Health My Data Act or a cyber-insurance questionnaire, and how much remediation the first scan turns up. Projects such as a Conditional Access redesign are quoted separately, and terms run month to month.
Do you offer cybersecurity consulting or only managed security services?
Both, and they often run in sequence. Consulting covers a defined piece of work: a risk assessment, an insurance questionnaire, a Microsoft 365 hardening project, an incident-response plan or a review of how a software firm separates production from corporate systems. Managed security is the ongoing part: endpoint detection and response, monitoring, patching, phishing training and monthly reporting. A Bellevue firm with its own IT staff can keep daily administration and hand us detection, response and after-hours coverage, with the split written into the agreement.
Is the free external penetration test really free?
Yes, and it is the only free offer we make. Engineers test your internet-facing systems remotely, within a scope you approve in writing: your public IP addresses, firewall, VPN, remote-access portals and exposed services. You receive a written report of what was reachable and what should be fixed first. It does not include internal testing, social engineering or remediation, which are scoped separately. For many Bellevue offices it finds an old VPN appliance or a forgotten remote-desktop port that an attacker would find the same way.
What does a security program look like for a ten-person Bellevue office?
Smaller than most people fear. Our published five-person office case study, an engagement outside Washington, shows the baseline: managed detection and response on every device, multifactor sign-in with no exceptions, a password manager, email filtering, encrypted laptops, phishing training and backups that cannot be altered by ransomware. For a ten-person firm that adds up to a few weeks of setup and then routine monitoring. The controls that matter most cost little; the expensive part is usually cleaning up shared accounts and old admin access first.
See what an attacker sees before they do.
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
