Peekr security scanner for container images

Developers and users of software containers will find it easier to integrate security into their development and delivery cycle, and remove obstacles to enterprise adoption.

Scalock, the leader in scalable security solutions for containerized environments, announced today the release of Peekr™, a free-of-charge software-as-a-service tool for scanning container images, available at

Peekr provides a quick, easy and reliable way to ensure that images are secure by comparing them against a database of 5 million common vulnerability signatures, including language-specific signature in Python, Java, Javascript, PHP and Ruby, in addition to Linux distribution packages (RPM and DEB). The scanner can also be used to scan Docker images on DockerHub, CoreOS Quay, and also supports v1 and v2 private registries.

In addition to scanning images for vulnerability assessment, Peekr relies on Scalock’s Active Container Inspection™ technology to test images in a secure sandbox, looking for any suspicious activity patterns or malicious behavior, such as abnormal use of resources and network port scanning which might otherwise go undetected even in images free from known vulnerabilities.

“With the rapid adoption of container technology in DevOps environments, the need for better security is top of mind for many organizations,” said Amir Jerbi, Co-founder and CTO of Scalock, “By offering an accessible security scanner, we hope that developers and users of containers will find it easier to integrate security into their development and delivery cycle, and remove obstacles to enterprise adoption.”

Users can sign in to Peekr using their Google or GitHub accounts, initially getting ten scans per month, but they can increase this quota by inviting others to use Peekr. When a new user accepts a referral, five additional scans will be added to both parties’ monthly quota.

Scalock was founded and is backed by IT security veterans with the aim of securing containerized environments. The company’s comprehensive solution is currently in private beta, and Peekr represents a small subset of the capabilities that Scalock will provide upon general availability. Organizations interested in becoming beta customers can request to join here:
