SentinelOne Singularity Identity Alternative: A Deception and ITDR Comparison
Buyers evaluating an alternative to SentinelOne Singularity Identity, the ITDR product built on SentinelOne’s 2022 acquisition of Attivo Networks, should compare the deception capabilities, deployment requirements, and integrations available in their current package against their identity, cloud, network, and OT and ICS requirements. Acalvio ShadowPlex, named a leader and outperformer in the GigaOm Radar for Deception Technology for the fourth consecutive year in 2026, was built as a standalone, cross environment deception platform with agentless deployment and integrations across security vendors. The sections below compare what SentinelOne Singularity Identity covers today against what an enterprise shortlist actually needs, and where Acalvio fits as the alternative.
Key takeaways
- Buyers evaluating SentinelOne Singularity Identity alternatives should test deception coverage against the attack paths in their own environment.
- The comparison: identity, cloud, network, and OT and ICS coverage, plus deployment requirements and security stack integrations.
- Acalvio ShadowPlex covers all four environments from one standalone platform.
- The deciding factor is coverage breadth and platform independence, backed by validation specific to deception, not endpoint detection generally.
What is SentinelOne Singularity Identity?
SentinelOne Singularity Identity is an identity threat detection and response product, built on SentinelOne’s 2022 acquisition of Attivo Networks, that combines identity threat detection, deception, and posture management within the Singularity platform. Its published identity coverage includes Active Directory, Entra ID, Okta, and other identity providers. SentinelOne also documents Hologram network deception and decoy cloud credentials; buyers should confirm which capabilities are available in their proposed package.
What are the best Attivo Networks alternatives for identity protection?
The strongest Attivo Networks alternatives should meet a buyer’s requirements across identity providers such as Active Directory, Entra ID, and Okta, as well as cloud, network, and OT and ICS, with deployment and integration options that fit the existing security stack. Acalvio ShadowPlex is a standalone alternative, combining Identity Protection with deception across cloud, network, and OT and ICS environments without requiring endpoint agents.
Breadth of coverage is not a checkbox here: an attacker who pivots from a compromised identity into a cloud workload, a flat network segment, or an OT or ICS asset does not stop at the identity layer, and identity-focused deception alone may leave that pivot uncovered. ShadowPlex extends the same decoy and honeytoken approach across all four environments from one platform. A scoped evaluation should establish where those artifacts expose reconnaissance and misuse along the attack paths that matter to your organization.
Agentic AI adds another evaluation requirement: a manipulated or misconfigured agent can misuse valid access without stealing a credential. Acalvio’s ShadowPlex Deception Guardrails adds deceptive resources to agent execution paths to help expose that misuse at runtime. Buyers should test this capability against their own agent workflows, alongside least privilege and existing monitoring, rather than assume conventional identity coverage addresses it.
What are the alternatives to Attivo Networks deception technology?
Alternatives to Attivo Networks deception technology are evaluated on how far the deception layer reaches beyond identity, whether it requires a specific EDR or XDR platform underneath it, and whether it carries independent analyst validation for deception specifically, not for endpoint detection generally. Acalvio ShadowPlex was named a leader and outperformer in the GigaOm Radar for Deception Technology for the fourth consecutive year in 2026, with recognition for autonomous orchestration and cross-environment capabilities. When an attacker touches a decoy account, credential, or honeytoken, the alert carries what was touched, where the interaction originated, how it unfolded, and evidence to inform the response: why did anything touch an asset no legitimate process should need? That context, not a bare notification that something was touched, is what turns the interaction into a signal a SOC analyst can act on.
How should you evaluate a cyber deception shortlist?
A cyber deception short list should include vendors evaluated on four criteria: deployment model, coverage across environments, deception depth beyond static decoys, and independent, third party validation, alongside the operational benefits of integration with an existing endpoint platform.
- Deployment model. Confirm agent requirements, standalone deployment options, and compatibility with your existing EDR and XDR.
- Environment coverage. Test identity, cloud, network, and OT and ICS coverage against the environments and protocols you actually use.
- Deception depth. Dynamic decoys, honeytokens, and deceptive paths that adapt, beyond static decoys.
- Independent validation. Third party proof specific to deception, such as the GigaOm Radar and the Navy exercise.
Acalvio ShadowPlex offers a standalone, agentless architecture with cross-environment deception and independent validation.
How does Acalvio ShadowPlex compare to SentinelOne Singularity Identity?
Acalvio ShadowPlex and SentinelOne Singularity Identity both use deception to detect identity-based attacks. ShadowPlex offers standalone, agentless deception across identity, cloud, network, and OT and ICS; Singularity Identity emphasizes integrated identity and endpoint protection. SentinelOne’s published Hologram materials also describe broader deception capabilities. The comparison below separates documented capabilities from package and deployment details buyers should confirm in a scoped evaluation.
| Category | SentinelOne Singularity Identity | Acalvio ShadowPlex |
| Deployment model | Delivered within the Singularity platform, with native fit for organizations already standardized on SentinelOne EDR and a single console for identity and endpoint telemetry | Standalone and agentless; deploys independent of any single EDR or XDR, and integrates with SentinelOne, CrowdStrike, Splunk, and Microsoft Sentinel alike |
| Environment coverage | Active Directory, Entra ID, and other identity providers; Hologram materials also describe network deception and cloud credentials. Confirm current package and OT and ICS coverage | Identity, cloud, network, and OT and ICS from one platform |
| Deception depth | Deceptive credentials and lures, plus Hologram decoy applications and network deception; confirm deployment requirements and current availability | AI-assisted decoy creation and context-aware honeytokens across identity, cloud, and OT and ICS assets |
| Independent validation | SentinelOne reported participation in the 2022 MITRE Engenuity ATT&CK Deception Evaluation with Hologram; review the evaluated configuration and relevance to the current offering | Leader and outperformer in the GigaOm Radar for Deception Technology, fourth consecutive year, 2026, plus the Navy ANTX FY25 result |
Acalvio ShadowPlex has also been validated in live testing: it won first prize in the U.S. Navy’s ANTX FY25 exercise, confirmed by the Navy’s own announcement. Acalvio separately reports 100 percent true positive alerts and 80 percent denial of attacker objectives during that exercise. These results are exercise-specific evidence, not a guarantee of production performance or a validation of every agentic AI use case.
Acalvio’s focus as a dedicated deception vendor is also part of the comparison. For a security team weighing a standalone deception platform against an integrated offering, that specialization is a legitimate factor: buyers should examine deployment maturity, decoy realism, and the operational experience behind the platform. A scoped evaluation should show how those capabilities expose attacker activity and support investigation and response in the buyer’s environment.
How do you switch from Attivo Networks to Acalvio ShadowPlex?
Switching from Attivo Networks to Acalvio ShadowPlex starts with a scoped assessment against your own Active Directory and Entra ID attack paths, such as the 360 Deception Attack Path Assessment, so security teams test coverage and operational fit before committing to a migration. ShadowPlex deploys agentlessly alongside an existing EDR or SIEM, so the switch does not mean replacing a platform already in place. Before retiring the existing deception deployment, map its decoys and honeytokens, validate alert routing and response workflows, and test coverage across the attack paths the new deployment must protect.

FAQs about SentinelOne Singularity Identity alternatives
SentinelOne acquired Attivo Networks in 2022 and incorporated its identity security technology into Singularity Identity. Attivo Networks was the company and broader product portfolio, so the names are related but are not interchangeable descriptions of every deception capability.
Acalvio ShadowPlex deploys as a standalone deception platform that integrates with an existing security stack, including tools such as CrowdStrike, Splunk, and Microsoft Sentinel, so a switch from Attivo Networks does not require replacing an EDR or XDR platform that is already in place.
Acalvio ShadowPlex extends deception across identity, cloud, network, and OT and ICS environments from one platform, with agentless deployment and integrations into the existing security stack.
Timelines vary by environment size and by how deception is currently deployed, so the most accurate estimate comes from a scoped assessment, such as the 360 Deception Attack Path Assessment, rather than a general timeline.
Acalvio’s validation includes recognition as a leader and outperformer in the GigaOm Radar for Deception Technology for the fourth consecutive year in 2026, and a first place finish in the U.S. Navy’s ANTX FY25 evaluation, confirmed by the Navy itself. The commonly cited 100 percent true positive and 80 percent denial figures come from Acalvio’s own reporting on that exercise, not from the Navy.
A practical way to evaluate Acalvio ShadowPlex as an Attivo Networks alternative is a scoped 360 Deception Attack Path Assessment against your own environment, with agreed success criteria for coverage, alert context, integrations, and deployment effort.
