Open Source CyberArk Alternatives

Vault gives a system one interface for every secret it needs, whether that is a database credential, an API key for an external service or a certificate. The difficulty it addresses is bookkeeping: knowing who reached which secret is already platform specific and awkward, and adding key rolling, encrypted storage and an audit trail on top usually means a custom solution nobody wants to own.

Instead, secrets are read through Vault, which enforces tight access control and records a detailed audit log of every request. Storage backends vary, from local disk to Consul and others.

What matters is how secrets are issued and taken away.

• Secure storage: arbitrary key and value pairs encrypted before they are written, so raw storage access is not enough to read them.
• Dynamic secrets: credentials generated on demand for systems such as AWS or SQL databases, then revoked automatically once the lease ends.
• Encryption without storage: data encrypted and decrypted by Vault while living elsewhere, letting security teams set the parameters and developers keep ciphertext in a SQL database.
• Leasing and renewal: every secret carries a lease, with built in APIs for clients to renew before it expires.
• Revocation: single secrets or whole trees revoked at once, for instance everything read by one user, which helps with key rolling and with locking a system down after an intrusion.

Vault is written in Go and builds from source once the toolchain is in place. HashiCorp publishes documentation, tutorials, example applications in several languages and a certification exam.

JumpServer is a bastion host, an open source privileged access management platform that puts a controlled door in front of infrastructure rather than handing engineers direct credentials. DevOps and IT teams request access on demand and reach the target from a web browser, with no local client to install or maintain.

The product is assembled from several components that together form its operations management and security control framework, and a single platform fronts endpoints that would otherwise each need their own access path.

The protocols it brokers are the ones operations teams touch daily.

• SSH: Shell sessions to Linux and Unix servers through the browser.
• RDP: Remote desktop connections to Windows machines without a desktop client.
• Kubernetes: Cluster access mediated by the same platform and the same policies.
• Databases: Database endpoints reached under the same controls as everything else.
• RemoteApp: Published applications delivered to the browser rather than the workstation.

Getting started needs a clean 64-bit Linux server with at least four cores and eight gigabytes of memory. A quick start script from the latest release installs everything, after which the web interface answers on the server address with a default administrator account whose password should be changed at once. JumpServer is developed by FIT2CLOUD under GPLv3, and a community Grafana dashboard exists for teams that want to monitor it.

Werbot replaces the shared spreadsheet of server passwords and private keys with one sign-on that fans out to everything a team can reach. Users connect with their login and a private key, and every session on a connected host is logged and recorded as a screencast, so who did what stays answerable afterward.

It is written in Go, runs as microservices in Docker containers, and installs nothing on the target machine. The stack pairs an API service, a gRPC service, an authentication service and a background worker with Postgres, Redis, HAProxy and automatic certificates.

Coverage spans the protocols and platforms a mixed estate actually contains.

• Protocols: SSH, Telnet, RDP and VNC connections all pass through the same gateway.
• Providers: dedicated, VPS and cloud servers sit in one account, with fast import from AWS, Google and Azure.
• Containers: Docker and Kubernetes workloads are managed alongside plain hosts.
• Databases: MySQL, MariaDB, PostgreSQL, Redis, MongoDB and Elasticsearch are reachable through the same layer.
• Compliance: recorded sessions and collected logs gather the evidence security certifications ask for.

Setup wants Docker Compose, a domain with DNS access and Cloudflare credentials, after which one make target validates DNS and generates secrets. The project is still at version zero and warns that backward compatibility is not guaranteed before 1.0. Source is under the Business Source License, which allows what Apache 2.0 allows except reselling the product as a cloud service.
