Encryption In Transit: What It Is & Why It Matters

What it is

Encryption in transit protects data while it is moving from one place to another, for example between a user's browser and a server, or between two systems exchanging information. It scrambles the data as it travels so that anyone able to observe the connection sees only unintelligible content rather than the real information.

This addresses a different risk from encryption at rest. Data in motion can pass through networks and equipment outside an organisation's direct control, where it might be intercepted or tampered with. Encryption in transit is designed so that even if traffic is observed, it cannot be read or quietly changed.

How it works

At a general level, the two systems first agree on a shared secret in a way that an observer cannot easily reproduce, then use that secret to encrypt everything that passes between them. Many implementations also confirm the identity of the server, so the user can be confident they are connected to the genuine destination rather than an impostor.

Well-implemented encryption in transit typically provides:

• Confidentiality, so intercepted traffic cannot be read.
• Integrity, so any tampering with the data is detectable.
• Authentication, so the parties can confirm who they are talking to.

Strong practice favours current, widely trusted protocols and retires older, weaker ones. As with stored data, the protection is only meaningful if it is applied consistently to every connection that carries sensitive information.

Why it matters for debt recovery

Debt recovery involves moving sensitive information: a debtor accessing a portal, staff using internal systems, or data exchanged with authorised parties. Each of these journeys is an opportunity for interception if the connection is not protected. Encryption in transit closes that opportunity by keeping the data unreadable while it travels.

It also helps protect against tampering and against being tricked into sending information to the wrong destination. Together with encryption at rest, it ensures that data is protected both where it is stored and as it moves. For a prospective client, encryption in transit is an essential expectation for any service handling personal or financial data.

What to ask a provider

Useful questions explore how consistently and how well data in motion is protected:

• Is data encrypted in transit for all connections carrying debtor information?
• Are current, widely trusted protocols used, and are older weak ones retired?
• Is the identity of servers confirmed so users connect to the genuine destination?
• Does this protection extend to connections with any third parties?

A provider that applies strong encryption to every sensitive connection, including those with external parties, is offering more assurance than one that protects only some paths.

How Merion approaches it

Merion follows good practice by protecting sensitive information as it travels between systems, so that it remains private and unaltered in transit. As a general principle, connections that carry debtor data are secured using recognised, current protections rather than left exposed on the network.

The exact protocols and settings are reviewed and updated as standards advance, so we describe our position at the level of principle. You can read more about how stored and moving data are protected in the Trust Centre, and verify the controls that apply today by contacting us.
