Your Business Is Under Constant Threat

The increase in cyber threats has changed how networks and devices need to be managed. Today’s network infrastructure is more complex, requiring IT teams to constantly adapt and respond to ensure their core network, data, and IT assets are safe from threats. Security management involves meeting stringent industry and government regulations and compliance. Cybersecurity demands advanced security expertise and management. In fact, according to Gartner, the average cost of IT downtime is $5,600 per minute.
