Cybersecurity Services — Serving Sussex Since Day One
Your employees are your biggest security risk. We turn them into your strongest defense.
Over 90 percent of successful cyberattacks start with a human being clicking a phishing link — no firewall stops that. Powerful IT Systems, headquartered right here in Sussex, puts security awareness training and monthly phishing simulations at the core of our cybersecurity services, turning your employees from your biggest vulnerability into your strongest defense. We also deploy endpoint detection and response, advanced email filtering, managed firewalls, and DNS protection on every device we manage, monitored 24/7. When a real incident occurs, our engineers can be at your Sussex office in minutes for hands-on response. We support HIPAA, PCI-DSS, and CMMC compliance frameworks. Full cybersecurity stack included in every plan, no contracts.

Quick IT Tips
Practical advice for Sussex businesses — whether you work with us or not.
- •Run an internal phishing test before investing in any cybersecurity platform. If more than 10% of your Sussex team clicks a simulated phishing email, training needs to be your first priority — not more hardware.
- •Enable multi-factor authentication on every account that supports it. MFA blocks over 99% of account compromise attacks. If your Sussex business isn't using MFA on email and cloud applications, fix this today.
- •Your Sussex business should have a written incident response plan that every employee knows exists. When a breach happens, the first 30 minutes determine whether it's a minor event or a catastrophe.
- •Check whether your cyber insurance policy requires specific security controls. Many policies now mandate endpoint detection, MFA, and employee training. If you don't have them, your claim could be denied.
- •If your employees use the same password for work accounts that they use for personal accounts, you have a serious vulnerability. Require unique passwords and use a business password manager.
