Cisco vs Realm Security

About Realm Security

Realm Security sells a SOC-aware Security Data Pipeline Platform, abbreviated SDPP. The Realm Platform is the company's SOC-aware security data pipeline. The Realm Platform connects any source and sends data to any destination. Realm Security gives security teams independent control over their telemetry before it reaches the SIEM, data lake, or AI agent. Realm Security sits upstream of the SIEM, data lake and AI agent, shaping telemetry before it reaches any of them. Realm Security is owned by no SIEM or destination, so customers can switch or consolidate downstream tools later without re-instrumenting.^[1][2][3]

Realm Security describes legacy pipelines as shuttling raw data logs between tools, leaving analysts buried in irrelevant telemetry and budgets consumed by SIEM ingestion costs. Realm Security cites the 2025 SANS SOC Survey, which found that 42% of SOCs send all incoming data into a SIEM, often without a retrieval or management plan. Realm Security states that pipeline tools are increasingly being acquired by the SIEM vendors whose growth depends on volume flowing into their platforms.^[6]

Realm Clarity AI understands what each source produces and what each destination needs, then shapes the flow between them. Clarity AI profiles every source at the field level and models what each destination can consume. Recommendations are shown with a match rate and run in a pending state against live data before they go active. Clarity AI does the analysis and the customer's team approves the changes. When Clarity AI is trained on a source, the customer receives source-specific, personalized reduction and redaction recommendations, vetted by Realm's security research team and shown with a match rate before the customer acts.

Realm Security reduces, enriches, redacts and transforms data on the rules a customer approved. Realm Security strips low-value, noisy telemetry before it reaches the SIEM. Realm Security injects context as logs pass through, so events arrive carrying the where and who. Realm Security normalizes disparate vendor formats into one schema, then shapes the same source differently for each destination. Privacy Guard discovers and masks PII, PHI, and PCI in transit without altering structure, so parsers and detection logic keep working. Authorized investigators can retrieve unredacted values from Data Haven. Data Haven keeps a complete, searchable copy and allows any event to be resupplied. Telemetry cut from the SIEM is retained in Data Haven as a complete, searchable copy. Detection Integrity proves that a data cut did not cost a detection. Realm checks every reduction against the customer's live detections.^[1][3][8]

Realm Security ingests data across firewall, endpoint, identity, email and cloud sources. Any source that can deliver over a standard transport, such as syslog, an HTTP webhook, or S3, can connect using Custom CEF, JSON, or Syslog. For sources Realm pulls from, such as Salesforce, Realm manages the integration for the customer. A format-agnostic Collector and managed parsing onboard new sources without engineering on the customer's side. Schema drift detection catches source changes before they break parsing. Realm sends to Splunk, Microsoft Sentinel, Cortex XSIAM, CrowdStrike NG-SIEM and Sumo Logic, along with data lakes and archives.

Realm Security is deployed in about a week and is run by the SOC team itself. Realm manages the infrastructure while the customer's SOC owns the decisions. Realm automates filtering rule creation, configuration, routing decisions, and much more. One customer connected FortiGate firewalls feeding Sumo Logic and let Clarity AI shape the stream for what the destination needed. A Fortune 500 materials science company selected Realm to reduce SIEM ingestion costs without sacrificing detection coverage and to prepare its data layer for AI-driven SOC workflows.^[1][6][8]

Realm Security is headquartered in Boston. Realm Security was founded by Peter Martin, Jeff Kraemer and Sanket Choksey. The founders played roles in creating, launching and scaling technology solutions for Carbon Black, Rapid7, Confer Technologies and Cisco Systems. Realm Security, Inc. raised $5 million in seed funding from Accomplice and Glasswing Ventures, announced September 12, 2024. Realm Security announced a $15 million Series A funding round led by Jump Capital, with participation from Glasswing Ventures and Accomplice. Realm Security announced a $2M strategic investment from Presidio Ventures, the corporate venture arm of Japanese-headquartered Sumitomo Corporation. Realm Security plans to use the investment to accelerate its Asia-Pacific expansion through channel partners and strengthen its executive team. Realm Security expanded its Realm Partner Program with the addition of Crush Security and ProCern Technology Solutions in North America. Crush Security is a cybersecurity VAR, and ProCern is an MSSP that integrates the Realm Platform into a fully managed data pipeline service.^{[1][2][3][6][10]}
