The Risks of Outdated Phone & Network Infrastructure 

In today’s connected environment, poor communication systems don’t just affect productivity — they compromise security, credibility, and compliance. 

  • Security Vulnerabilities  Unsecured VoIP systems and unsegmented networks can expose your business to voice phishing, SIP-based attacks, and unauthorized access to sensitive communications. 

    Operational Downtime  Dropped calls, unreliable internet, or unresponsive systems result in frustrated staff and missed opportunities — especially in deadline-driven environments.

    Compliance Gaps For DoD contractors, communication systems must be built with compliance in mind. Poorly configured networks may violate CMMC, NIST 800-171, or other DFARS requirements. 

    Lack of Flexibility Legacy phone systems often lack remote capabilities, call routing features, or proper access controls — creating bottlenecks in day-to-day operations.
