Network Security for Business

Your business network carries sensitive data every second of the day, from customer records and financial transactions to internal communications and proprietary files. Protecting that network from unauthorized access and malicious activity is not optional; it is a business necessity. Unio Digital provides network security services that keep Tucson-area businesses safe and operational.

Common Network Security Threats

Malware and Ransomware

Malicious software can enter your network through email attachments, compromised websites, or infected removable media. Ransomware is especially damaging, encrypting your files and demanding payment for their release. Without proper network defenses, a single infected device can compromise your entire organization.

Unauthorized Access

Weak passwords, misconfigured access controls, and unpatched vulnerabilities give attackers pathways into your network. Once inside, they can move laterally across systems, escalate privileges, and exfiltrate data without detection if monitoring controls are not in place.

Denial of Service Attacks

Distributed denial of service (DDoS) attacks flood your network with traffic, overwhelming resources and making services unavailable to legitimate users. While large enterprises are frequent targets, small businesses are increasingly affected as attack tools become more accessible.

Essential Network Security Controls

Firewall Configuration and Management

A properly configured firewall is the first line of defense. Beyond basic port filtering, modern firewalls inspect traffic at the application layer, block known malicious domains, and enforce policies based on user identity. Regular rule reviews ensure the firewall stays aligned with your changing business needs.

Network Segmentation

Segmenting your network into separate zones limits the blast radius of a security incident. For example, isolating guest Wi-Fi from your production network, or separating point-of-sale systems from general office traffic, prevents an attacker who gains access to one segment from reaching others.

Intrusion Detection and Prevention

Intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor network traffic for suspicious patterns and known attack signatures. When threats are detected, these systems can alert administrators or automatically block malicious traffic in real time.

Monitoring and Incident Response

Security is not a set-it-and-forget-it proposition. Continuous network monitoring tracks traffic flows, identifies anomalies, and provides the visibility needed to detect threats early. A documented incident response plan ensures your team knows exactly what to do when a security event occurs, minimizing damage and recovery time.
