Attivo Networks (SentinelOne)

What Attivo Networks actually does

Attivo built its reputation on deception technology—deploying fake credentials, fake systems, and fake data that look real to attackers but serve as tripwires. When an attacker touches a decoy, the alert fires with near-zero false positives because legitimate users have no reason to interact with decoys. This approach catches post-compromise activity that traditional perimeter tools miss entirely.

The identity detection and response (IDR) capabilities focus on Active Directory. Attivo identifies exposed credentials, misconfigured AD objects, shadow admins, and attack paths before adversaries exploit them. It also conceals real credentials and injects deceptions into the environment to misdirect attackers who’ve already gained a foothold. Think of it as turning your network into a minefield for anyone moving laterally.

Since the SentinelOne acquisition, Attivo’s technology has been folded into the Singularity platform. The deception and identity capabilities are now features within SentinelOne’s broader XDR offering rather than standalone products. This means stronger integration with endpoint detection but less flexibility to run Attivo alongside a competing EDR.

Who it’s best for

• Enterprises with Active Directory environments where identity-based attacks are the primary concern
• Security teams with mature detection stacks that want a deception layer to catch what EDR and SIEM miss
• Organizations already running SentinelOne who can activate identity features without adding another vendor
• Incident response teams that want high-fidelity alerts with minimal false positives from deception-based detection
• Regulated industries facing advanced persistent threats where lateral movement detection is a board-level concern

Pricing reality check

You can no longer buy Attivo as a standalone product. It’s bundled within SentinelOne’s Singularity platform, typically at the higher license tiers. If you’re already a SentinelOne customer, adding identity and deception features is an upsell conversation. If you’re not a SentinelOne customer, adopting Attivo means adopting SentinelOne’s entire endpoint platform.

That bundling math works in your favor if you were evaluating SentinelOne anyway. It works against you if you’re committed to CrowdStrike or Microsoft Defender for Endpoints and just wanted the deception technology. In that case, you’re looking at standalone deception vendors or building the capability differently.

Alternatives to consider

• Acalvio — Pure-play deception platform that works alongside any EDR. More flexibility if you don’t want to switch endpoint vendors.
• CrowdStrike Identity Protection — Identity threat detection built into the Falcon platform. The obvious choice if you’re already a CrowdStrike shop.
• Illusive Networks (Proofpoint) — Another acquired deception vendor, now part of Proofpoint’s identity portfolio. Similar trajectory to Attivo.
• Microsoft Defender for Identity — Covers AD-based attack detection within the Microsoft 365 Defender suite. Less sophisticated deception but zero additional cost if you’re licensed.

The Charting Cyber take

Attivo’s technology is genuinely clever. Deception-based detection produces some of the cleanest alerts in security—when someone touches a fake credential, that’s not a false positive. The identity exposure assessment for Active Directory fills a gap that many organizations don’t even realize they have until a red team walks through their AD misconfigurations in an afternoon.

The acquisition complicates things. If SentinelOne is your EDR, this is a no-brainer add-on. If it’s not, you’re making a platform decision disguised as a feature decision. Don’t rip out a working EDR to get deception technology. Evaluate the full SentinelOne stack on its own merits, and treat the Attivo capabilities as a bonus rather than the sole justification for switching.
