How they differ

Mars Security sells Mars, a platform for hunting across log sources, cloud and endpoint data without ingestion pipelines. Mars connects to an existing security stack by API, with no data ingestion and no tool replacement. Realm Security sells the Realm Platform, a SOC-aware security data pipeline that connects any source and sends data to any destination. CISO Tribune also files Realm Security under SIEM and Data security posture management.

Realm Security's other products include Clarity AI, which profiles sources at the field level, Detection Integrity, which checks every reduction against live detections, and Privacy Guard, which masks PII, PHI and PCI in transit. Realm Security sits upstream of the SIEM, data lake and AI agent, and says it is owned by no SIEM or destination. Mars Security, by contrast, says teams can build, test and ship detections directly against live data. Mars Security announced Real-Time Intel-Based Detection on September 8, 2026, a capability that turns newly published threat intelligence into validated detection rules within minutes of release.

Realm Security is headquartered in Boston. Realm Security raised $5 million in seed funding from Accomplice and Glasswing Ventures, announced September 12, 2024, and later announced a $15 million Series A led by Jump Capital. It also announced a $2M strategic investment from Presidio Ventures, the corporate venture arm of Sumitomo Corporation. One Realm Security customer is a Fortune 500 materials science company that selected Realm to reduce SIEM ingestion costs. On October 29, 2026, Realm Security added Crush Security and ProCern Technology Solutions to its Realm Partner Program in North America.

What Detection Integrity does[1][8]
Detection Integrity proves that a data cut did not cost a detection. Realm checks every reduction against the customer's live detections.

About Mars Security

Mars Security provides Mars, a platform for hunting across log sources, cloud and endpoint data and for building and testing detections without ingestion pipelines.

Mars Security says Mars lets security teams hunt across every log source, cloud, and endpoint without moving a byte. The company states that Mars deploys in hours with zero ingestion pipelines to build or maintain, so teams can query their entire environment from day one, with full organizational context across every asset, user, and activity.[1][2]

For detection engineering, Mars Security says teams can build, test, and ship detections directly against their live data, without the lag of traditional pipelines slowing the engineering cycle.[2]

Mars Security describes a second aim: aligning a security program to the threats that are targeting an organization right now, rather than last quarter's incidents. The company says that in an era where attacks move at machine speed, detection and response has to match. Mars Security says the goal is to get ahead of adversaries, demonstrate proactive defense, and close the gap between the program and the real world.[2]

On connectivity, Mars connects to an existing security stack by API, with no data ingestion and no tool replacement. Mars Security says Mars connects to any source with an API.[1][3]
