Protei (NTC Protei / Nauchno-Tekhnicheskiy Tsentr Protei)
Protei is a Russian telecommunications software and hardware company founded as NTC Protei (OOO Nauchno-Tekhnicheskiy Tsentr Protei) in St. Petersburg in 2002 (INN 7825483961, OGRN 1027809185227). It builds carrier core-network systems plus DPI, web-filtering and SORM-compatible lawful-intercept products; commercial sales are also run through an affiliate operating from Amman, Jordan. IDENTITY NOTE (verified): a separately incorporated, name-related St. Petersburg entity, OOO Protey Spetstekhnika / Protei ST (INN 7802471913, OGRN 1097847159321, incorporated 3 June 2009), is the entity on the U.S. OFAC SDN List (added 2024-05-01 under E.O. 14024). Per public corporate records aggregated by OpenSanctions, NTC Protei is recorded as the parent/owner of Protey Spetstekhnika; the two are nonetheless distinct legal persons, and the OFAC designation attaches to Protey Spetstekhnika, not to NTC Protei. On the public record the OFAC designation should not be conflated with the commercial DPI vendor NTC Protei, which itself carries no U.S./EU designation. Treasury's May 1, 2024 press release (jy2318) characterizes Protey Spetstekhnika as developing telecommunication systems for the Russian Ministry of Defense; the OFAC SDN record itself lists the designation under program RUSSIA-EO14024 without that descriptive language.

Government designation status
No active designation on public record
As of the research date (2026-06-22), the commercial DPI/lawful-intercept vendor NTC Protei (INN 7825483961) has NO designation on public record from any in-scope authoritative source: it is not on the US OFAC SDN List, the US BIS Entity List, the US Treasury NS-CMIC investment list, the EU consolidated sanctions list, or the US FCC Covered List. (The FCC Covered List was verified to contain only Huawei, ZTE, Hytera, Hikvision and Dahua and their subsidiaries/affiliates; no Protei entity appears on it.) The only government listing found for this specific entity is on Ukraine's NSDC sanctions register, which falls outside the authoritative-source set specified for this database. A name-related but separately incorporated St. Petersburg company, OOO Protey Spetstekhnika / Protei ST (INN 7802471913, a.k.a. PROTEI ST LTD), IS on the OFAC SDN List, verified at OFAC Sanctions List Search detail id=48657 (program RUSSIA-EO14024, effective 2024-05-01, designated under E.O. 14024 sec. 1(a)(i) for operating in the technology sector of the Russian Federation economy). That designation is recorded against Protey Spetstekhnika and is deliberately NOT attributed to NTC Protei here, to avoid guilt by association. No customer/deployment claims and no individual PII are reported in this record.
This dossier restates public government-designation records; it is not an allegation of wrongdoing by AI Analytics, and it publishes no customer-deployment claims or targeting data. A designation describes a specific legal action by a named authority — read its scope; an export control, an equipment-authorization restriction, and an asset-blocking sanction are not the same thing.
