ShellArmor is a Linux server SSH security platform operated by Averta Security, positioned as “kernel-level SSH Protection.” By installing a lightweight agent, it monitors, scores, and responds to PTY keystrokes, authentication events, file writes, lateral movement, and more in real time—without replacing your existing SSH setup. The company highlights eBPF hooks, tamper-resistant hash-chain session recording, and millisecond-level blocking capabilities.
In terms of protection, it covers SSH session monitoring, threat detection, automated response, key lifecycle management, FIM/MAC, host health, and compliance auditing. Typical actions include automatically sending SIGKILL to dangerous sessions, temporarily banning IPs via iptables/nftables, blocking writes to critical files, and host isolation. Deployment is via a Linux agent, with the sample install command being a one-line curl piped to bash. It supports Ubuntu, Debian, RHEL, CentOS, Rocky, AlmaLinux, Amazon Linux, Oracle Linux, SUSE, and Fedora, requires kernel 4.15+, and claims memory usage under 20MB.
On the management side, it provides a SOC Dashboard, real-time session viewing, threat scores, alerts, Fleet Health, service downtime notifications, audit trails, RBAC, project grouping, policy editing, a REST API, and a mobile app. Integrations include Okta, Microsoft Entra ID, Google SSO, Slack, PagerDuty, Webhook, Syslog, SIEM/SOAR, and email alerts. For compliance, the text states that it can generate reports related to SOC 2, PCI-DSS, HIPAA, FedRAMP, and ISO 27001, but this is more like report-mapping capability and does not mean the product itself is certified.
The Free plan is permanently free but limited to 1 host. Pro costs $25/server/month when billed annually, or $35 when billed monthly. Enterprise is custom-priced and includes longer retention, SIEM/SOAR, multi-tenancy, SLA, immutable session records, FIM, compliance reporting, and more. Incident response and vulnerability monitoring each add $5/server/month. Compared with Teleport, Wazuh, fail2ban, Falco, and similar tools, ShellArmor’s selling point is combining SSH attack-chain protection, blocking, and auditing into a single agent.
The main advantages are that deployment does not change the familiar ssh user@host workflow, and its real-time response capabilities are strong. It is suitable for environments with multiple Linux hosts, SRE teams, security teams, and enterprises that need SSH auditing. The downsides are its deep reliance on Linux/eBPF, while many enterprise-grade capabilities are placed in the Enterprise tier. Keystroke capture and session recording also involve privacy and compliance disclosure requirements, so rollout must be handled carefully.
The collected text does not provide information about mainland China nodes, ICP filing, network connectivity, or local payment options. The only payment methods seen are Stripe and PayPal, so access from China is rated unknown. If network, compliance, or payment constraints are an issue, alternatives to evaluate include a self-hosted Wazuh, Teleport, and Falco/fail2ban stack, or domestic host security, bastion host, and SIEM/SOC products.
