Authentication establishes identity.
Transaction Assurance establishes trust.
Authentication proves who entered the account. Transaction Assurance cryptographically proves every high-risk action before it executes.
THE PRINCIPLE
Trust shouldn’t be inherited. It should be proven.
Why Traditional Authentication
Can’t Prove the Action.
Traditional MFA creates trust at the session level which can be stolen and re-used.
SLC provides continuous proof for every action inside a session.
FIRST PRINCIPLES
By moving cryptographic proof into the SIM Secure Element, SLC establishes trust where software alone cannot.
HOW IT WORKS
SLC Guardian fuses live context, hardware security, and human approval to cryptographically prove every high-risk action.
THE SHIFT
Authentication proves access. Authorization proves the action.
Logging in proves someone got into the account. It doesn’t prove the right person approved the wire transfer, the beneficiary change, or the payout. That gap, between getting in and the action itself, is where fraud now lives.
Building Together
Building the future of digital trust.
Together with leaders across identity, mobile, payments, connectivity, and enterprise infrastructure.
THE AI ERA
Built for humans and the agents acting for them.
AI agents and automated systems now initiate real actions — payments, changes, approvals. SLC proves the authorization behind every one, human or machine, so autonomy never means unaccountable.
BUILT TO INTEGRATE
Built to work with the identity infrastructure you already have.
SLC Guardian complements your existing identity, access, and authentication investments. No rip-and-replace. No disruption. Just a security layer that proves every action.
Stronger security. Zero disruption.
SLC Guardian plugs into your workflows through simple APIs and provides real-time, step-up assurance for the actions that matter most.

INSIGHTS
From the SLC blog.
Friction Isn't the Real Problem. Wrong-Layer Authentication Is.
Payment friction kills customer lifetime value — but most of the friction conversation misses the real cause. A look at why authentication friction is an infrastructure problem, not a UX one.

The Rails Are Built. The Trust Layer Isn't.
Latin America has built world-class payment rails. But fraud losses are scaling alongside adoption — because the identity layer underneath was never upgraded. A look at the trust gap shaping the next phase of digital payments.

Phishing-Resistant MFA: What It Actually Means and Where the Industry Falls Short
CISA calls phishing-resistant MFA the gold standard. But FIDO2 keys and passkeys only solve half the problem. Learn what phishing-resistant authentication actually requires — and what's still missing.
