Avoid Costly Incidents –
Performant, Scalable Protection

Detection and visibility for your infrastructure doesn’t need to come with massive overhead and false positives delivered by traditional Windows EDR products. Unlike existing solutions, Capsule8 is specifically built to protect enterprise Linux systems.

Capsule8 provides your team with ops friendly visibility, detection and response that embeds seamlessly into Linux systems – regardless of environment. By using Capsule8, your team has the visibility needed to help them detect incidents, and investigate and protect against unwanted behavior, without adding operational risk or cost.

Linux Detection
Incident Investigation
Cloud Native Protection
Runtime Container Security
Regulatory Compliance
Flexible Deployment
Identify sophisticated attacks as they happen. Detect unwanted activity without requiring a kernel module, orchestration, baselining or system scans. Have fewer false positive alerts, reduce triage, investigation, storage and network costs, while providing more assurance of security posture.

Detections include: Malware Targeting Linux, Memory Corruption, New File Behavior, Unusual Application Behavior, Suspicious Interactive Shell, Container Escapes, Kernel & Userland Backdoors, Privileged File Operations, Network Discovery, Lateral Movement, Process Injection, System Discovery, Scheduled Task Changes, Compiler Usage, Privileged Command Usage and Risky Developer Activity
Gain real-time visibility into security-relevant data and investigate incidents with meaningful, near-real-time telemetry, without the gathering and querying negatively impacting workload stability and performance. See exactly what logged-in users do on your infrastructure without risking performance issues on live systems.

No matter what mix you are of on-prem legacy systems, public and private cloud, or microservices and containers, Capsule8 protects your infrastructure as it looks now and as you continue to evolve it.
Capsule8 provides detection and resilience for Linux systems in any environment, including container runtimes such as Docker, containerd, and CRI-O. Our detection is crafted with the threat models of cloud-native systems in mind and pinpoints workloads, not just hosts.

Capsule8 allows you to create custom policies leveraging container metadata, so you can extend protection to meet the concerns of your unique environments. For instance, you can restrict the ability for specific containers to write new files, run new programs after startup, read cloud metadata, have multiple users running, make outbound network connections, or spawn shells.
Achieve and enforce a compliant Linux enterprise whether governed by PCI, HIPAA, FINRA, or FedRAMP with a single solution for your production environment. Apply policies around privileged access to systems (PAM) and file integrity monitoring (FIM). Capsule8 Protect supports compliance requirements while driving down noise.

For teams wanting to leverage their existing operations workflows, you can integrate Capsule8 into your existing automation, orchestration, log management, and incident response tooling.

For those who prefer a zero-overhead graphical interface, Capsule8’s SaaS deployment allows you to manage the agent and detection policies via a hosted console.

Security designed for lower operational resources and less downtime risk

Avoid costly downtime, overloaded hosts, or stability snafus caused by traditional security tools by enabling resource limits (including CPU, memory, and data collection limits) and running without a kernel module.

A single host-based agent designed for uptime, scalability and reliability protects all of your Linux hosts and nodes in any environment — whether workloads you operate in clouds or data centers.

The most transformative organizations rely on Capsule8 for detection, monitoring and response
Adedayo Adetoye Senior Manager Security Architecture and Engineering
“We wanted a comprehensive host-based intrusion detection and response system that is capable of giving us deep visibility into what is happening within our environment as well as capability to respond in a systematic way to potentially malicious behaviour.

Capsule8 provides us with a powerful set of fundamental building blocks for hardening our security posture through its standard and custom detection capabilities that we can write.”
Adam Fest Head of Security Engineering, Databricks
“Capsule8 is helping to increase alerting, monitoring, and prevention in Databricks’ platform to protect our environments. Our close collaboration with the Capsule8 team has made integrating their product painless.”
