IT certification verification: blockchain secured credentials
Is this document real? Check it here
Paste the verification link or the ID printed on the document, or upload the file. You get the answer here in seconds, with no account.
IT certifications decide who gets hired and who gets access to production systems, and the paper version of one proves nothing about itself. TRUE issues certifications as blockchain secured digital credentials that a recruiter, a client or a security team can verify by scanning a QR code, including whether the credential is still current.
TL;DR
Verifying an IT certification means confirming with the issuing body, not judging the document by eye. A blockchain secured credential does that automatically: scan the QR code or open the verification link, and the page confirms the holder, the certification, the issuing body and whether the credential is currently valid. TRUE issues certifications that way, writing a cryptographic fingerprint of each one to a blockchain at issue, so an altered name, level or date fails the check instead of passing. Verification takes seconds, needs no account, and works whether the verifier is a recruiter, a client or a security team granting access.
- Scan to verify. QR code or link, seconds, no login and no phone call to the issuing body.
- Status, not just issue date. The page shows active, expired or pending renewal.
- Fixed at issue. An edited certificate no longer matches the blockchain record.
Why is IT certification verification broken?
Because the credential and the proof are separate things, and only the credential travels with the candidate. CISSP, AWS and CompTIA certifications carry real weight in hiring and access decisions, but the artefact presented is usually a PDF or a printout that cannot demonstrate its own authenticity.
Paper certificates prove nothing
A printed certificate is a design. It carries no mechanism that lets a verifier test whether the issuing body ever issued it.
PDF certificates are no better
A PDF can be edited with ordinary software. Change a name, move a date, upgrade a level, and the result looks identical to the real thing.
Manual checks do not scale
Calling certification bodies takes time an HR team processing dozens of candidates does not have, so the check gets skipped and the risk gets accepted.
Expiry goes unnoticed
Many IT certifications need renewal. A certification earned five years ago may no longer be valid, and a printed certificate has no way to say so.
How often do employers check credentials at all?
Less often than the hiring process implies, and the gap is widening as falsification gets easier. Independent UK research finds most organisations outside the largest employers do not verify every academic credential, while the share of employers seeing fraudulent applications is rising. Meanwhile security teams report that missing skills, not missing headcount, is what hurts.
- Only 52% of large employers verify all academic credentials, dropping to 37% at medium sized and 29% at small organisations, while 45% of large employers have caught an applicant giving false qualification information. Source: Prospects Luminate, from a YouGov survey of more than 500 HR decision makers, fieldwork 24 to 29 April 2025.
- 18% of UK adults say they have lied on a CV or job application. Published by Cifas, the UK fraud prevention service, on 3 February 2025, from an Opinion Matters survey of 2,000 UK adults.
- 88% of cybersecurity professionals reported at least one significant consequence from skills shortages, and 95% reported at least one skill need on their team. Source: ISC2 2025 Cybersecurity Workforce Study, published 4 December 2025, based on 16,029 respondents.
Put those together and the shape of the problem is clear. Teams need specific proven skills, and the document that claims those skills is the one nobody has time to check.
How does blockchain verification work for a certification?
The issuing body writes a cryptographic fingerprint of the credential to a public chain when it issues. Verifying recomputes that fingerprint from the document in front of you and compares the two, which either matches or does not. There is no judgement call and no dependence on the issuer answering the phone. If the certification was issued through TRUE, paste its verification link into TRUE Verify and the comparison runs there and then.
1. Issue on chain
The credential is created with all its details and its fingerprint is written to a blockchain.
2. Cryptographic security
The record is held across thousands of independent computers, so no single party can rewrite it.
3. Verify by scan
Scan the QR code or open the verification link. Confirmation appears in seconds.
4. Live status
Expiry and renewal state are shown at the time of the check, so expired credentials are marked as expired.
Which IT certifications can be issued this way?
Any certification where the issuing body controls the credential, across security, cloud, networking and general IT. The categories below are the ones customers issue and verify most.
Cybersecurity
CISSP, CISM, CEH, CompTIA Security+, OSCP, GIAC.
Security certifications carry the highest stakes, because hiring on one means trusting someone with sensitive systems. A cryptographic check replaces a plausible looking PDF.
Cloud
AWS Solutions Architect, Azure Administrator, Google Cloud Professional.
Cloud certifications stand behind skills an organisation depends on. Verify before a contractor touches the environment, not after the misconfiguration.
Networking
CCNA, CCNP, CCIE, CompTIA Network+, Juniper JNCIA.
Network certifications prove someone can run enterprise infrastructure, which is worth confirming before granting access to it.
General IT
CompTIA A+, ITIL, PMP, Agile and Scrum credentials.
Foundation certifications establish baseline knowledge. Instant verification makes checking them routine rather than optional.
Who verifies IT credentials, and why?
Recruiters before an offer, clients before a project, and internal teams before a renewal deadline passes. Each has the same requirement: an answer now, without waiting on a certification body.
Hiring verification
HR scans the QR code on a candidate's credential and the check completes on the spot, so the hiring decision does not wait on a verification backlog.
Partner and vendor certification
Partners share credential links that verify instantly, and clients see current certification status including continuing education rather than a snapshot from years ago.
Freelancer credentials
Independent professionals attach verifiable credentials to profiles and proposals, so every prospective client can confirm them without calling anyone.
Internal team tracking
One dashboard shows team credentials with alerts before expiry, which turns recertification into a scheduled task rather than an audit finding.
What does the platform provide for certification bodies?
Automation into the systems that already hold the data, plus the lifecycle features a certification with a renewal cycle needs. Issuing is only half the job; keeping status accurate is the other half.
API integration
Connect to HRIS, ATS or LMS through five endpoints. Most integrations complete in one to two weeks.
Bulk verification
Upload a list of credentials for a team or a candidate pool and get verification results back.
LinkedIn sharing
Professionals add credentials to LinkedIn as verifiable links rather than static images.
Continuing education
Track credits and requirements, so verifiers see current standing rather than the original award.
Expiry alerts
Automatic notifications before a credential lapses, for both the holder and the issuing body.
Portfolio view
All of a professional's certifications in one verifiable place.
What is the technical basis?
Four established blockchain networks for redundancy, European compliance standing, and an independently certified security posture. Verification does not depend on one chain remaining available.
Ethereum
The largest smart contract blockchain.
Polygon
High throughput with Ethereum security.
Avalanche
Sub second finality.
Fantom
High throughput at scale.
eIDAS compliant
EU electronic identification and trust services standards.
Proof of stake
Energy efficient consensus.
Cyber Hygiene Certified
Independently certified by OneMore Secure.
Swedish company
GDPR native, European data handling by design.
What do certification bodies and employers ask?
The questions below come up most often from issuing bodies and hiring teams. For the general case, see our guide to checking whether a certificate is fake or real.
How do expired IT certifications appear when verified?
The credential carries its expiry date, and the verification page shows the status at the moment of the check: active, expired or pending renewal. A verifier sees the current position rather than only the original issue date, which is the difference that matters for certifications on a three year renewal cycle.
Does TRUE track continuing education requirements?
Yes. Credentials can carry continuing education credits and requirements, so a verifier sees whether the holder has kept up with ongoing obligations rather than only that they once passed an exam.
Does TRUE integrate with HR systems?
Yes. The REST API has five endpoints and connects to HRIS, ATS and LMS platforms so credential data flows into the systems recruiters already use. Most integrations complete in one to two weeks.
Is there an API for bulk verification?
Yes. The API supports bulk operations for organisations checking large numbers of credentials at once, such as a contractor pool or an acquired team.
Can a certification be revoked after issue?
Yes. The issuing body controls status, so a revoked certification verifies as revoked. The original record stays on the chain, which means the history is visible rather than erased.
What do TRUE customers say?
“For us, it’s only natural to collaborate with the player in secure document management that has the highest quality, and stands for world-class security.”
“The animation looks fantastic, and it’s so simple for our recipients. It has made things much easier for us at Sitevision with the digital certificates.”
