Telesign provides cloud-based authentication and verification services through SMSSMSShort Message Service, the protocol built into cellular networks for sending text messages between phones; cyber tools use it for alerting, two-factor authentication delivery, or phishing simulation over mobile channels., voice, and push notifications for securing user identity.
Summary
Telesign is a commercial identity and fraud prevention platform delivered as a set of hosted APIs that application teams call directly from their own signup and login flows rather than installing anything locally. Its request-log tooling lets developers replay recent calls and inspect timing, status, and user-agent details through an interactive console, which suggests the target user is an engineer integrating verification into a product rather than a SOCSOCA security operations center, the team or function that monitors threats, investigates alerts and coordinates incident response. Its work can be internal, outsourced or shared. analyst monitoring a network. It sits in the identity-access space, alongside phone verification and SMS messaging services rather than endpoint or network security tools. Telesign has been running since 2005 and its documentation is actively maintained, with the request-inspection pages last updated four months ago and ten releases in the window we track, suggesting a mature, still-updated service rather than an abandoned one.

How Telesign helps
Is this signup coming from a real, reachable phone number or a disposable one?
scores the phone number against carrier and line-type intelligence and returns a risk verdict the calling code can check before issuing a one-time code
Did the verification code I just sent actually reach the user?
records delivery status per message so the calling code can look up whether a given code was delivered, undelivered, or still pending
Which of my users logging in right now look like fraud rather than a real customer?
returns a risk score built from phone, device, and account signals that the calling code can act on before granting access
Why did this specific user get blocked at signup?
the request log lets the call be replayed and its timing, status, and user-agent inspected to see which check produced the rejection
Which login attempts are coming from numbers that were just reassigned or recycled?
checks the number against carrier line-type and history data and flags it as a mismatch risk before the code is sent
Are my verification API calls actually reaching Telesign, or failing silently?
the interactive console shows status and timing for recent calls so a silent failure shows up as a missing or errored entry rather than nothing

Five scores for Telesign, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
Release-note detail over time

Each offering on the pricing page links to its own page of plans, read at its latest capture.
Plan relaunches
Plans, prices and descriptions are quoted from the vendor's own pricing page as we read it on each date. A plan missing from a later reading is shown as no longer listed on the page — a statement about the page, not the product. Readings that failed to show any plans are left out rather than read as a change.

How we count
Read from 7 of 15 release notes and docs updates we hold for Telesign. "First seen" is the earliest note that names something; "last" is the latest. Our history may start partway through Telesign's life, so an old integration can show a recent first-seen date.
Each change counts once: "added 40 checks" is one line, so the numbers measure how often coverage moves, not how big the catalogue is or how well it detects.
