SSH Key Auditing

Track SSH keys,
and who uses them

SSH keys pose serious risks to Linux, including unauthorized access and stealthy lateral movement. Sandfly tracks critical SSH assets agentlessly. We call this capability SSH Hunter.

With SSH Hunter, all SSH public keys are tracked and traced. Security teams can see where keys are being used, who is using them, when they first appeared, and what they allow access to across all systems instantly.

Use Cases


Know where SSH keys are

A stolen SSH key can allow instant access to your entire infrastructure. Sandfly ensures SSH keys only allow access where they should and new keys do not show up unexpectedly.


Safeguard embedded devices

SSH keys can allow silent access to embedded devices. Know who and what has access to these systems with Sandfly.


Monitor Linux appliances

Linux appliances often present a black box to security teams. Sandfly can gain access to these systems and let you see what SSH access is being allowed instantly.


Key and server risks

Sandfly can identify SSH key risks such as duplicate keys or weak keys using older algorithms. We also have policy checks to detect vulnerable settings on your SSH servers.


Key timeline

Our SSH timeline provides a window into key movement and activity. Sandfly shows you when keys were first seen, last seen, or even if they vanished and returned at a later date.

Track SSH key use and abuse

Being agentless, Sandfly will automatically find and track SSH keys without any user intervention or risk to remote systems. Once we identify keys, they are tracked and customers can use a variety of tools to stay on top of SSH credential use and abuse.

The SSH Key Explorer allows you to visually see where a key is being used across your Linux fleet, who is using the key, when it was created, how old it is, and much more. You get an instant view of what SSH keys are in use across your network.

Sandfly's SSH Key Explorer

Rapid incident response

If you are responding to an incident, knowing what SSH credentials are in use is critical. SSH keys are high value targets for intruders and allow rapid compromise across an enterprise. With Sandfly's agentless scanning for SSH keys, you get instant knowledge of this critical piece of forensic data even if no monitoring is currently in place. Sandfly will automatically locate SSH keys on hosts and build an instant overview of what is happening with them to save precious time when investigating an incident.

SSH Duplicate Keys Alert

SSH key auditing made easy

SSH Hunter also tracks keys and looks for unusual behaviors such as duplicate keys, orphaned keys, and more. Our key timeline shows you the first time we saw a key, and when that key was seen on other hosts. You will know at a glance if a new key is being used unexpectedly or if old keys are still present on any host.

SSH credential compromise presents significant risks that demand a proactive, performance-conscious solution. Sandfly Security offers an agentless approach to protect your SSH environments, track assets, and ensure comprehensive security without compromising system performance.
