Why Network Security Matters to Your Business
Network threats affect businesses of all sizes. Cyberattacks, data theft, and internal breaches now target small and mid-sized companies across the D.C. Metro area. As attackers grow more sophisticated, basic protection is no longer enough.
According to Barracuda Networks, employees at businesses with fewer than 100 staff members face 350% more threats than those at larger organizations. Without clear policies and secure systems, your business remains exposed.
To stay ahead of these risks, you need structured security policies and trusted protection. Our team at CSU offers network security solutions designed to minimize your exposure and enhance your defenses. Let us help you develop a customized security plan that suits your business and keeps you one step ahead.
How Can I Improve My IT Security?
Most cyberattacks don't start from the outside. They begin with unauthorized access, weak passwords, or unmonitored employee activity. Unfortunately, many IT security companies still focus only on external threats.
Our IT network security services are built to protect your business on all fronts. As a trusted network security solutions company, we provide full access control and endpoint protection, so you always know who is connected to your systems. This level of visibility reduces risk and strengthens compliance across your network.
Network Access Control (NAC)
Network access control consolidates all your endpoint protection tools—whether it's antivirus software, intrusion prevention, or securing laptops and mobile devices—and applies consistent rules to every connection.
With identity and access management, users must verify their identity through two-factor authentication before gaining access to your systems, data, or internal resources. CSU provides enterprise-level network security solutions that help protect your business from unauthorized access and evolving threats.
Antivirus & Malware Protection
Antivirus and malware protection are essential, but many businesses do not realize their true value until a threat causes real damage. A single infection can disrupt operations, corrupt files, or expose sensitive data.
Our advanced endpoint security solutions utilize proactive detection to block and remove harmful software before it can spread. With CSU, your systems stay protected against viruses, spyware, and other malicious programs that target your network. Don't leave your systems open to external threats, and prepare for virus and malware attacks.
Application Security
You rely on your tools every day—they should not put your business at risk. As a trusted network security solutions company, CSU keeps your systems, applications, and equipment updated with the latest patches.
Ongoing updates are a core part of our managed network security services. This reduces risk, closes security gaps, and protects your business from avoidable threats. It's a critical part of any strong network and security services strategy.
Email Security
Email is one of the easiest ways hackers access business data, especially through weak or default passwords. A trusted network security company must do more than basic filtering to keep you protected.
Our managed network security services include robust password enforcement, email virus scanning, and real-time phishing detection and alerts. As part of our comprehensive network security solutions, we also provide cybersecurity training to mitigate human error and detect threats early.
