Cyber threats are growing more complex and relentless. From ransomware to data breaches, many Seattle businesses struggle to keep up with modern security demands.
The cost of falling behind? Reputational damage, legal penalties, and lost business.
And let’s face it: internal IT teams often don’t have the resources or time to manage 24/7 security operations.
That’s why many companies in the Pacific Northwest are turning to Managed Security Service Providers (MSSPs). These specialized IT partners monitor your systems round-the-clock, detect threats early, and keep your business protected.
At Intelligent Technical Solutions (ITS), we help organizations throughout Seattle (and across the country) harden their cybersecurity posture with proactive monitoring, compliance support, and tailored IT services. We’re a nationally ranked MSSP and part of CRN’s Fast Growth 150 and Top 250 MSSP lists in 2025.
In this article, we’ll break down:

What to Look for in a Seattle MSSP

- 24/7 threat monitoring and incident response
- Compliance expertise (HIPAA, SOC 2, CMMC, etc.)
- Cybersecurity consulting tailored to your industry
- Local presence backed by national scale
- Clear, scalable pricing and service transparency
