Fidelis Network DLP - 2026 Pricing, Features, Reviews & Alternatives

Fidelis Network DLP is a network-based data loss prevention solution that monitors network traffic to detect and prevent unauthorized transfer of sensitive information within enterprise environments. The solution employs patented Deep Session Inspection technology to analyze content across encrypted and unencrypted traffic channels in real time. It serves organizations in sectors such as defense, healthcare, finance, information technology, education and government where stringent data protection and regulatory compliance are required. The platform safeguards intellectual property, financial records, personally identifiable information and other confidential assets while aligning with regulatory requirements including GDPR, HIPAA, PCI DSS and CCPA.

At the core of Fidelis Network DLP is Deep Session Inspection which extracts and reconstructs content traversing the network to uncover hidden data exfiltration attempts concealed within normal traffic flows. The system continuously monitors all ports, protocols and applications while performing deep metadata analysis of more than three hundred attributes to identify anomalies and unauthorized access patterns. Contextual analysis of keywords, patterns, file types and metadata enables detection of sensitive data in transit. The solution inspects email traffic, file transfers and web interactions to surface potential threats and track how data moves between internal and external endpoints.

Policy-based controls allow organizations to define and enforce data protection rules that automatically block or alert on suspicious transfers. Customizable classification criteria support tailored definitions of sensitive information based on business needs. Real-time alerting notifies security teams of policy violations and potential breach attempts. Behavioral analysis correlates user intent and access patterns to detect insider threats and data misuse before exposure occurs. Encryption and data masking features further ensure that sensitive content remains protected even when transfers are authorized under policy.

Fidelis Network DLP integrates with existing security ecosystems through open standards such as Syslog, SNMP, CEF, LEEF and SMTP to provide unified visibility into threat activity and data movement. The platform supports hybrid deployments across cloud and on-premises environments and leverages API connectivity for custom integration with orchestration and incident response workflows. Comprehensive reporting capabilities facilitate audit and compliance reviews by documenting adherence to internal policies and regulatory mandates. Scalable architecture is designed to handle high network traffic volumes while offering intuitive management interfaces that reduce operational complexity for security teams.
