About Acalvio

Acalvio sells ShadowPlex, a deception platform built to operationalize 360 Deception at enterprise scale. ShadowPlex deployment is agentless across identity, cloud, network, endpoints, and OT/ICS. Acalvio extends preemptive defense across identity, cloud, OT, advanced threats, agentic AI, and targeted threat intelligence. Acalvio has four ShadowPlex offerings powered by 360 Deception, its approach to preemptive cybersecurity and disruption of AI-driven attacks. Built on 360 Deception, the Acalvio platform unifies preemptive threat detection across identity, cloud, and modern environments. The Acalvio platform uses dynamic deception, honeytokens, deceptive credentials, and evolving attack paths to expose malicious activity before attackers can escalate access or gain control.[1][3][4][6][9]

360 Deception goes beyond decoys to manipulate the signals attackers and autonomous systems rely on to validate targets, credentials, and movement paths. Preemptive cyber deception works to deny, deceive, and disrupt before the attacker reaches impact.[3]

ShadowPlex Advanced Threat Defense uses AI-powered deception to surface stealthy attacker behavior during reconnaissance, lateral movement, and privilege escalation. Advanced Threat Defense correlates detected behaviors to MITRE ATT&CK TTPs for rapid investigation. ShadowPlex integrates AI into every phase of deception, from network discovery to adversary analysis. ShadowPlex operates agentlessly across IT, cloud, and OT environments, deploying deception assets without interfering with production traffic or operations.[5]

ShadowPlex uses deception to protect credentials at rest and in use, exposing misuse, lateral movement, and privilege escalation. ShadowPlex automatically recommends token types, volume, and placement based on Active Directory structure and endpoint characteristics.[6][7]

ShadowPlex Cloud Security delivers AI-powered deception and honeytokens to IAM and cloud-native services across public clouds. ShadowPlex Cloud Security is deployed via native cloud APIs and protects cloud-native workloads and IAM infrastructure. ShadowPlex Cloud Security unifies threat detection across AWS, Azure, and GCP with no agents. ShadowPlex Cloud Security places deception in identity repositories like Instance Metadata and Secrets Store. Acalvio CDR is agentless and API-driven, and integrates directly with cloud control planes and infrastructure services. Acalvio CDR delivers detections enriched with adversary behavior context to a SIEM, SOAR, or XDR platform.[9]

ShadowPlex Targeted Threat Intel provides threat intelligence from external-facing decoys, including APIs and IPv6 IIoT devices, to detect reconnaissance and credential attacks early. ShadowPlex Targeted Threat Intel delivers threat intelligence with IPs, credentials, and attack patterns. ShadowPlex Targeted Threat Intel uses decoys for web apps, APIs, and IPv6 IIoT services to detect reconnaissance and credential attacks. ShadowPlex Targeted Threat Intel shares indicators in real time in STIX and other standard formats. ShadowPlex Targeted Threat Intel is delivered as a managed cloud service or as an on-premises/cloud appliance. When delivered as a service, Acalvio hosts and manages the decoys, isolating attacker traffic from the production network. Acalvio integrates with CrowdStrike Falcon® Identity Protection, Splunk, Microsoft Sentinel, and other SIEM/SOAR solutions. Acalvio integrates with EDR/XDR platforms including CrowdStrike Falcon, Microsoft Defender, Palo Alto Cortex XDR, and VMware Carbon Black, and with SIEM/SOAR solutions.[1][6][10]

Acalvio plants honeypots and honeytokens across sensitive systems, without disrupting operations. Acalvio baits insiders with decoy assets such as files, credentials, or systems to trigger early warning before critical assets are touched. Acalvio engages ransomware early with deceptive assets that expose encryption behaviors. Acalvio uses deception as an enforcement layer to expose policy violations and unauthorized access.
