What it sells: RapidFort

What RapidFort Analyzer does[1][2][5]
RapidFort Analyzer delivers validated vulnerability intelligence across images, registries, CI pipelines, and clusters. RapidFort Analyzer enumerates all files, packages, and configurations within container images, not just those reported by package managers. RapidFort supports SBOM export in SPDX, CycloneDX, JSON, and CSV. RapidFort Analyzer identifies when vulnerabilities originate from base images and recommends near-zero CVE Curated Images as drop-in replacements.
What RapidFort Optimizer does[1]
RapidFort Optimizer removes unused components using runtime-validated intelligence, delivers hardened runtime images, and supports configurable hardening presets. RapidFort rebuilds optimized images every 24 hours and delivers them as drop-in replacements without CI/CD changes. RapidFort offers Light, Standard, and Aggressive hardening levels. RapidFort hardens at the container image layer without modifying code.
What RapidFort CART does
RapidFort CART continuously evaluates container environments against approved security benchmarks, detects drift, and generates remediation guidance with audit-ready evidence. RapidFort CART uses the OpenSCAP framework to evaluate workloads against recognized security benchmarks and organizational baselines.

What it sells: VulnCheck

What Exploit & Vulnerability Intelligence does[1][4][5][10][11][15]
Exploit & Vulnerability Intelligence is offered for decisions on which vulnerabilities need immediate remediation. It gives early access to new vulnerability information not found in the NVD, along with dozens of unique fields. It includes an exploitation timeline covering when a vulnerability was first disclosed, when evidence of exploitation was first discovered and when it was remediated.
What Initial Access Intelligence does[1][5][8]
VulnCheck develops exploit PoCs, packet captures, and Suricata signatures in house. They are used to defend against initial access vulnerabilities.
What VulnCheck for Government does[16]
VulnCheck for Government includes features, functionality and data. They are available only to VulnCheck's Government partners.

About RapidFort

RapidFort sells a single platform that combines runtime visibility, secure image foundations, vulnerability analysis, automated hardening, and compliance validation. RapidFort's platform combines curated near-zero CVE container images, aged application libraries, malware removal threat intelligence, runtime profiling, and attack surface management. RapidFort analyzes container software, prioritizes real security risks, and automates remediation workflows. RapidFort states that base images and open source dependencies introduce risk before development begins. RapidFort states that static scans do not show which components actually execute in production.[1][2][3][4]

RapidFort Analyzer delivers validated vulnerability intelligence across images, registries, CI pipelines, and clusters. RapidFort Analyzer analyzes container image contents, configurations, and real applicability context to produce vulnerability intelligence. RapidFort supports SBOM export in SPDX, CycloneDX, JSON, and CSV for audits, compliance, and customer security reviews. RapidFort Analyzer identifies when vulnerabilities originate from base images and recommends near-zero CVE Curated Images as drop-in replacements. RapidFort applies a Rapid Risk score to focus teams on vulnerabilities most likely to be exploited in the near term.[1][2][4][5]

RapidFort offers container images that are continuously patched and hardened before applications are deployed.[4]

RapidFort Profiler provides real-time runtime visibility into container behavior, revealing which components actually execute. RapidFort designs its runtime profiling for Kubernetes environments. RapidFort establishes expected runtime behavior and flags unexpected binaries, configurations, or execution patterns. RapidFort analyzes real runtime behavior to identify unused components and automatically removes unnecessary packages and dependencies. RapidFort Optimizer removes unused components using runtime-validated intelligence, delivers hardened runtime images, and supports configurable hardening presets. RapidFort offers Light, Standard, and Aggressive hardening levels that control how aggressively unused files, packages, and dependencies are removed. RapidFort rebuilds optimized images every 24 hours and delivers them as drop-in replacements without CI/CD changes. RapidFort Runtime uses agents and BPF/ptrace instrumentation to observe live application behavior, read-only and without requiring code changes. RapidFort continuously creates an inventory of executing software and detects runtime dependencies. RapidFort detects unexpected or unauthorized changes to packages, binaries, and processes.[1][2][4][5][6][7][8]

RapidFort CART continuously evaluates container environments against approved security benchmarks, detects drift, and generates remediation guidance with audit-ready evidence. RapidFort CART uses the OpenSCAP framework to evaluate workloads against recognized security benchmarks and organizational baselines. RapidFort integrates support for STIG and CIS security benchmarks used in regulated and mission-critical environments. RapidFort reduces inherited vulnerabilities, validates security baselines, and generates continuous compliance evidence.[4][9]

RapidFort supports vendors securing the software supply chain, from containerized SaaS to classified infrastructure. Defense Unicorns delivers software for defense missions, often in classified environments. Defense Unicorns used the RapidFort Platform to harden containers for proprietary products such as UDS Registry, an OCI-compliant registry launched in June 2025. The Modern Data Company provides customers with a data operating system to scale business transformation and AI. RapidFort, RAPIDFORT, and RBOM® are registered trademarks of RapidFort, Inc.[3][4][8][10][11]
