What it sells: SafeBreach

What SafeBreach Validate does[9]
SafeBreach Validate is a breach and attack simulation (BAS) product. SafeBreach says its breach and attack simulation tool helps enterprise security teams test the ability of deployed security controls to detect, prevent, and mitigate real-world attacks. SafeBreach says the BAS tool helps validate custom detections and incident response processes at scale.
What SafeBreach Propagate does
SafeBreach Propagate provides attack path validation capabilities. SafeBreach describes a CART tool designed to assess the potential impact and blast radius of a successful breach. SafeBreach says the CART tool helps uncover high-risk paths to critical organizational assets and crown jewels.
What SafeBreach CTEM Platform does
The SafeBreach Continuous Threat Exposure Management (CTEM) Platform is designed to help organizations move from reactive security to a proactive, closed-loop risk management program. The SafeBreach CTEM Platform uses SafeBreach Helm and three AI agents to operationalize the five-phased CTEM framework. SafeBreach says the SafeBreach CTEM Platform includes integrations with vulnerability management platforms, external attack surface management solutions, threat intelligence feeds, SOAR platforms, and ticketing and workflow management tools.
What SafeBreach Helm does[1]
SafeBreach Helm is the AI infrastructure layer of the SafeBreach CTEM Platform. Helm orchestrates three purpose-built AI agents, the Analyst Agent, Validation Agent, and SecOps Agent, through a single natural-language interface to operationalize the full CTEM lifecycle. Helm moves organizations from siloed security activities toward a closed-loop CTEM program that continuously identifies, prioritizes, and remediates cyber risk at scale.

What it sells: Tenzai

About SafeBreach

SafeBreach sells the SafeBreach Exposure Validation Platform, which combines the SafeBreach Validate breach and attack simulation product with the attack path validation capabilities of SafeBreach Propagate. SafeBreach says the complementary tools help security teams identify security control gaps and understand what an attacker could accomplish by exploiting them.[1][5]

SafeBreach says its breach and attack simulation tool helps enterprise security teams test the ability of deployed security controls to detect, prevent, and mitigate real-world attacks. SafeBreach describes a BAS tool designed to use the TTPs of malicious actors to test the efficacy of deployed security controls against real-world threats. SafeBreach says the BAS tool helps validate custom detections and incident response processes at scale.[6][7]

SafeBreach describes a CART tool designed to assess the potential impact and blast radius of a successful breach. SafeBreach says the CART tool helps uncover high-risk paths to critical organizational assets and crown jewels. SafeBreach says the CART tool helps prioritize remediation activities to focus on the most critical exposures.[7]

SafeBreach describes an automated remediation engine that suggests tailored remediation steps based on Validate simulation results. The remediation steps are specific to the customer's tech stack, taking into account deployed security controls and environmental context. SafeBreach says the recommendations are fully integrated into the SafeBreach platform, so they can be viewed without extra tools or dashboards. SafeBreach says the engine uses AWS Bedrock so that customer data is never shared or retained.[7]

SafeBreach Helm is the AI infrastructure layer of the SafeBreach CTEM Platform. Helm orchestrates three purpose-built AI agents, the Analyst Agent, Validation Agent, and SecOps Agent, through a single natural-language interface to operationalize the full CTEM lifecycle. Helm moves organizations from siloed security activities toward a closed-loop CTEM program that continuously identifies, prioritizes, and remediates cyber risk at scale. The SafeBreach Continuous Threat Exposure Management (CTEM) Platform is designed to help organizations move from reactive security to a proactive, closed-loop risk management program. The SafeBreach CTEM Platform uses SafeBreach Helm and three AI agents to operationalize the five-phased CTEM framework.[1][5][8]

SafeBreach says the SafeBreach CTEM Platform is grounded in an adversarial exposure validation (AEV) platform backed by a decade of enterprise expertise and 40,000+ attack simulations. SafeBreach says the CTEM platform unifies security data from across a security ecosystem into a 360-degree view of risk. SafeBreach Helm and the SafeBreach CTEM Platform are designed to work with an existing security stack. SafeBreach says the SafeBreach CTEM Platform includes integrations with vulnerability management platforms, external attack surface management solutions, threat intelligence feeds, SOAR platforms, and ticketing and workflow management tools.[8]

SafeBreach says it validates that each security control is operating optimally, both individually and in orchestration with other tools in the stack. SafeBreach runs continuous, automated attack simulations, or customers can build their own, across controls including web, endpoint, email, network inspection, network access, container, and cloud. SafeBreach identifies which controls blocked, detected, or missed attacks. SafeBreach maps attack simulation results to the MITRE ATT&CK framework to visualize how defenses performed. SafeBreach says its simulations are real attack methods that are executed only against SafeBreach simulators and never use real production data.[9][10]

SafeBreach says its customers face the challenge of extending security beyond the boundaries of the enterprise network to support a remote workforce. SafeBreach says the SafeBreach CTEM Platform was built for Fortune 500 and Global 2000 environments. The Husch Blackwell law firm used SafeBreach to run safe, automated attack scenarios that continuously validate the efficacy of security controls for endpoint devices. A Fortune 500 healthcare organization used SafeBreach to establish a stronger, more defensive posture with a proactive approach to critical threats. A Fortune 500 drug and device development company used SafeBreach to institute automated testing of its security architecture. SafeBreach says its SafeBreach Labs team is dedicated to uncovering new threats and conducting original research.[5][8][9][11][12]
