The platform addresses persistent automated attacks targeting internet-connected servers by deploying an open source agent that installs via a single command line execution. The lightweight agent operates with offline capability and consumes approximately fifteen megabytes of RAM while avoiding inbound network port requirements. The core protection mechanism aggregates threat intelligence from eight sources and maintains a database of over ninety-four thousand malicious IP addresses that updates hourly.\n\nThe firewall integration implements automated protective rules that block brute force attempts and scanning probes before they reach server services. The brute force protection system applies progressive banning with configurable thresholds and analyzes seven-day attack patterns to generate smart recommendations for security settings. The geoblocking feature enables restriction of traffic from more than two hundred countries at the firewall level while maintaining compatibility with IP whitelists. The web application firewall monitors web server logs in real time to detect SQL injection, cross-site scripting, remote code execution, path traversal and twelve additional OWASP-classified attack types without requiring manual configuration changes.\n\nThe vulnerability intelligence module automatically inventories installed software packages and versions, cross-referencing them against the National Vulnerability Database, the Known Exploited Vulnerabilities catalog and ten additional advisory sources to identify applicable CVEs with severity classifications, CVSS scores and active exploitation indicators. The security scanner generates a numerical score from zero to one hundred by auditing SSH configurations, firewall rules, web server headers, file permissions and automatic update settings. Clear remediation commands accompany each identified issue and scan history supports tracking over time. The Defensia Network feature enables collaborative threat intelligence sharing where banned IP addresses propagate automatically across an organization server fleet. The multi-server dashboard presents real-time event charts, ban timelines, geographic heat maps and server status indicators while the activity briefing delivers morning summaries of grouped overnight incidents with attack narratives.\n\nThe alert system supports email, Slack, Discord and custom webhook integrations with seven configurable trigger types including brute force attempts, server offline status and web application firewall detections. Schedules for daily and weekly email digests can adapt to local time zones and include threat analysis, blocked attack counts, server health metrics and security recommendations. Role-based access control defines Owner, Admin and Member roles while two-factor authentication uses TOTP compatible with major authenticator applications. Comprehensive audit logging delivers a full trail of actions for compliance purposes. The platform aligns with recognised cybersecurity frameworks for identify, protect, detect, respond and recover functions and supports systemd, Upstart and SysVinit initialization systems without dependency on external orchestration platforms or cloud provider APIs.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/18f5a394-5de4-4136-bb07-39db5894a987.png","url":"https://www.getapp.co.uk/software/2084513/defensia","@id":"https://www.getapp.co.uk/software/2084513/defensia#software","@type":"SoftwareApplication","applicationCategory":"BusinessApplication","publisher":{"@id":"https://www.getapp.co.uk/#organization"},"offers":{"price":"7","@type":"Offer","priceCurrency":"EUR"},"operatingSystem":"Cloud, Linux, Linux on premise"},{"@id":"https://www.getapp.co.uk/software/2084513/defensia#breadcrumblist","@type":"BreadcrumbList","itemListElement":[{"name":"Home","position":1,"item":"/","@type":"ListItem"},{"name":"Website Security Software","position":2,"item":"/directory/3786/website-security/software","@type":"ListItem"},{"name":"Defensia","position":3,"item":"/software/2084513/defensia","@type":"ListItem"}]}]}
