For executives and DX leaders

External IDs,
treated as an investment.

IDs issued to partners are a data-leak risk, a license fee paid every month, and the partner experience itself. Tactna brings the external ID lifecycle onto one platform and improves risk, cost, and experience at once. After people, the same mechanism extends to AI agents.

Problem

IDs you can't see
are risk
and cost.

30% zombie IDs are both a breach entry point and seats you keep paying for.

The more partner-facing apps your digital investments add, the more IDs you issue outside the company. Not knowing who can get into what is the probability of a security incident, the cost of unused seat licenses, and the revenue lost while partners wait.

  • 30%Unused IDsIn one customer, 30% of distributor IDs were unused. Each one is a key still in a leaver's hands.
  • ¥Seats you keep paying forSeat licenses cost the contracted amount whether used or not. Reclaimable seats exist; you just can't see them.
  • WeeksTime partners spend waitingThe weeks before a new distributor can use the app are lost sales and a partner's first impression.

How it is solved

Problem by problem,
what changes.

  1. 01

    Risk of a security incident

    Before

    Nobody can say exactly who can get into what.

    After

    Inactivity detection and auto-lock drive zombie IDs toward zero. Evidence goes straight to the audit.

  2. 02

    Wasted license fees

    Before

    You pay for contracted seats and can't see usage.

    After

    Seats and usage per app made visible. Reclaim unused seats and report savings monthly.

  3. 03

    Partner experience and lost revenue

    Before

    Weeks to onboard. Digital investments never pay off.

    After

    Same-day onboarding and a portal in your brand. Adoption visible per partner.

A day in that job

After go-live,
three moments.

  • Scene 01

    The day the board asks about security

    "How are external partner IDs governed?" Active rate from the dashboard, lock and delete history, and ISO 27001 / 27017 certification, answered in one report.

    The system keeps you audit-ready.

  • Scene 02

    The day the license renews

    Read the per-app usage report and cut contracted seats from 1,280 to 1,100. The monthly value of 176 reclaimed seats becomes the business case.

    Once you can see it, you can negotiate.

  • Scene 03

    The day you open AI agents to partners

    Hand distributor stock inquiries to an AI agent. The agent has an owner, role, apps, and expiry, managed in the same ledger as human users.

    From who to what. Same lifecycle.

FAQ

Before you buy,
what people ask.

How do we estimate ROI?

Estimate along three axes: seat-license fees you can reclaim, the effort of ID management (cut 70% in one case study), and the revenue from faster partner onboarding. Tactna's specialist team helps with the estimate before rollout.

Are our existing investments (IdP, IGA, apps) wasted?

No. Tactna does not replace your IdP, splits scope with IGA, and connects apps without rebuilding them. It adds the missing layer on top of what you have.

How far along is support for AI agents?

AI agents need an owner, a role, app access, and expiry too. Tactna's lifecycle model is designed to extend from human users to agents as is, and the roadmap is public.

Who uses Tactna?

Manufacturing (KITZ), information services (Fujitsu G-Search), education (CPA), insurance (MS&AD InterRisk Research). More than a million accounts, zero churn.
