    Fill Cybersecurity Gaps with Experts

    On Time & On Budget

    If needed, we can provide end-to-end protection through a dedicated Security Operations Center to identify and mitigate attacks on your behalf. We use proven risk-based strategies which reduce risk and minimize the impact of future attacks.

    Why Outsource Your Cybersecurity Program?

    Cost Savings

    It’s time consuming and expensive to recruit and retain top talent, not to mention that cybersecurity salaries and insurance premiums are skyrocketing.

    Operational Expertise

    Even your own cybersecurity professionals can only maintain expertise in so many areas. We can provide a team of experts to fill those critical gaps.


    Your cybersecurity expert will inevitably get sick, go on vacation or even leave your institution for a new opportunity. You can count on us 24/7, 365 to ensure continuous cybersecurity readiness.

    GreyCastle Security was founded over a decade ago on the principle that cybersecurity and effective defense is entirely possible if you use common sense, apply a system of measurement, and know what you’re trying to protect. We help organizations to develop effective cybersecurity programs, minimize the impact of state and federal compliance regulations, improve client retention, and mitigate security incidents. Our revolutionary approach to service delivery solidifies the business mindset that cybersecurity is not just an “IT” issue – it’s about the overall health of your business.
