TNB KEP

What TNB KEP does

TNB Teknoloji (legal name TNB Bilişim Teknolojileri Sanayi ve Ticaret A.Ş., formerly operating as TNB KEP) is a Turkish regulated electronic communications and digital trust services provider, headquartered in Ankara with a regional branch in Istanbul. The company was founded in 2012 as the first private organization licensed by the Information and Communication Technologies Authority (BTK) to provide Registered Electronic Mail (KEP / Kayıtlı Elektronik Posta) services, and it operates under Law No. 5070 on Electronic Signature and related KEP regulations. It is the technology arm of the Türkiye Noterler Birliği (Turkish Union of Notaries), which provides both shareholder alignment and a captive professional user base.

The product portfolio is built on a regulated electronic trust stack. Core offerings include KEP (registered electronic mail with cryptographic signing, timestamping, and proof of delivery), e-İmza (qualified electronic signature services via E-Güven, TürkTrust, E-Tuğra, and Aladdin hardware tokens), and e-Belge platforms Docsline and İzonay that integrate e-Notification (UETS), KEP, e-Signing, and e-Correspondence modules. Modulized add-ons include KEPLink and KEPGateway for access and enterprise integration, KEP İK for HR document delivery (payroll, contracts, leave), Toplu Belge İmzalama for batch PAdES-XL signing, and Zaman Damgası for timestamping. VOODOO provides no-code robotic process automation targeted at repetitive office tasks.

The business model is subscription- and license-driven. KEP is sold in tiered annual and multi-year plans (Mini through Mega, 50-500 messages and 250 MB-1 GB storage, with prices disclosed in Turkish Lira ranging from approximately 1,323 TL to 12,666 TL inclusive of 20% VAT). E-İmza is sold in 1-3 year certificate packages, E-Belge platform modules as enterprise licenses, and VOODOO and timestamping on subscription/licensing terms. Go-to-market combines direct enterprise sales through the Ankara headquarters and Istanbul branch, a nationwide authorized dealer network covering 28+ Turkish cities, an online self-service application portal for individuals and SMBs, and dedicated notary-focused channels including a special support hotline. Customers span banking (Yapı Kredi, Garanti BBVA, İşbank, ICBC Turkey, MUFG Bank, Anadolu Bank), insurance (Axa Sigorta, Groupama, Sompo, Anadolu Sigorta), healthcare (Acibadem), retail (Decathlon), defense (DMO), and the Türkiye Noterler Birliği, alongside individual consumer subscribers for personal electronic correspondence.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Logo Yazılım: Turkey's leading enterprise software vendor offering e-document and digital workflow solutions to SMBs and corporates; intersects with TNB's e-belge/Docsline offerings in integrated document workflow use cases.

Direct peers

• E-Güven: Turkish electronic certificate service provider that supplies e-İmza certificates to TNB's distribution but also sells directly, making it a parallel competitor in the qualified electronic signature market.
• Turkcell e-İmza: Turkey's largest mobile operator offers qualified electronic signature (e-İmza) services to consumer and enterprise segments, competing directly with TNB's e-İmza offerings on price and distribution reach.
• TürkTrust: Turkish certificate authority providing qualified electronic signature certificates and PALMA smart cards—competes with TNB's certificate distribution while also being a technology partner.
• PTT (Turkish Postal Service) KEP: Turkey's state postal operator offers KEP services as a licensed provider, directly competing with TNB Teknoloji in the same regulated domestic market with overlapping enterprise and government customers.
• E-Tuğra (e-Tugra): Turkish qualified electronic certificate service provider offering e-imza and digital certificate products, competing directly with TNB's E-Güven/TürkTrust-distributed signature services for both retail and enterprise customers.
• Vodafone Türkiye e-İmza: Major telecom providing e-İmza services through mobile signature partnerships, competing with TNB Teknoloji in the qualified electronic signature space for individual and corporate subscribers.

Broad incumbents

• DocuSign: Global leader in electronic signature and agreement cloud; competes with TNB in enterprise e-signature use cases for Turkish multinationals and EU-facing entities, though without local KEP regulatory integration.
• Adobe Acrobat Sign: Global e-signature and document workflow platform integrated with Adobe's document ecosystem; competes at the high end of enterprise digital signature workflows versus TNB's domestic KEP + e-İmza stack.

Regional players

• e-Dönüşüm (Turkish e-Transformation) Specialist Vendors: Specialist Turkish e-invoice, e-archive, and e-ledger software vendors serving the same regulated e-document market as TNB's Docsline platform; smaller scale but locally focused competitors.
