Communications archiving has transformed from a back-office checkbox into one of the most fiercely contested battlegrounds in regulated technology this year. Twelve months ago, the archive was little more than a footnote on a recorder vendor’s data sheet. Today, it sits at the heart of governance platforms across the industry — and with good reason.
According to Wordwatch, the catalysts are significant. End-of-life voice recorders were explicitly flagged as a systemic risk in the joint FCA, Bank of England and HM Treasury statement of 15 May 2026.
Wordwatch recently put together a buyer’s guide to compliance archiving and how to tell which propositions hold up.
DORA examinations have entered their second wave, and the designation of AWS, Azure and Google Cloud as critical ICT third-party providers in November 2025 has pulled recording infrastructure into scope for the first time. Add the FCA’s extension of Conduct Rules to non-financial misconduct, effective 1 September, and compliance and IT leads across every regulated firm are facing the same urgent question: what do we actually do about the archive?
Into this environment, two categories of vendor have rushed. Surveillance providers with established eComms and AI capabilities are now extending into archive modernisation, promising storage optimisation, migration tooling and broader governance coverage. Meanwhile, recorder vendors are repositioning legacy archive products as modern platforms. The buyer, who is rarely an archive specialist, must cut through considerable noise.
The right question to ask is not whether a vendor has an archive. It is whether that archive holds up against the reality of a mixed, multi-decade recorder estate when a regulator comes asking. Three tests separate a genuine archive modernisation platform from an archive-shaped feature bolted onto an adjacent product.
Test one: multi-recorder breadth across vendors and decades
Ask any vendor to list, by name and by version, every recorder they preserve in its original format — then compare that list against your own estate going back fifteen years. Most regulated businesses have used between three and five recorder vendors over that period. Several will now be end-of-support; some will have left the market entirely. The records, however, remain in scope under MiFID II’s five-to-seven-year retention obligations, under SEC Rule 17a-4, and increasingly under DORA’s resilience and exit-plan requirements.
A proposition that handles the current generation of recorders competently and classifies everything else as an ingestion problem to be scoped in a later phase is solving the wrong problem. The middle of any estate is easy. The edges — the unsupported recorder from 2014, the trader voice system from an acquired desk, the contact-centre platform decommissioned three CIOs ago — are where regulatory questions land and where retrieval projects fail. The test is specific: demand the vendor demonstrate, on your own estate, original-format preservation across every recorder vendor you have ever used.
Test two: original format with evidenced chain of custody
Storage optimisation — compression ratios, deduplication, tiered storage — is operationally necessary but evidentially insufficient. These are properties that tell you whether the archive is efficient. They do not tell you whether a record will hold up when a regulator’s expert opens it.
The defensibility question is whether the vendor can produce, for any record on any source, the original-format file with full chain-of-custody documentation, exportable in a format a regulator’s expert can independently verify. Each element of that phrasing carries weight. “Original format” was the standard the FCA’s August 2025 multi-firm review effectively applied when it flagged third-party vendor failures around outages, reconciliation gaps and missing data. “Chain of custody” is the test the DOJ’s Evaluation of Corporate Compliance Programmes applies when assessing whether communications evidence was preserved with integrity. “Independently verifiable” is what counsel demands during disclosure when audio quality becomes material to a case.
A vendor that has transcoded the original to an internal format — even a high-quality one — has made a decision the buyer must understand. That decision may be operationally defensible. It is considerably harder to defend evidentially, and it represents the wrong default for a system whose primary purpose is defensibility. Ask for a sample original-format export from a recording older than five years, on a recorder the vendor did not build. Then ask whether the export, the metadata and the chain-of-custody documentation would survive cross-examination.
Test three: decommissioning depth, not just data ingestion
This is where most archive modernisation propositions quietly fall apart. Real modernisation shrinks the legacy footprint. The recorder is retired. The maintenance contract is cancelled. The rack space is released. Engineering hours stop being spent on a system that should have been decommissioned years ago. The run-cost line falls in a way the CFO can see in next year’s budget.
Half-modernisation leaves the source recorder running, still under extended support, still generating cost, with an ingestion pipe to a new archive layered on top. The new archive feels modern. The old estate is unchanged. Total cost has risen, not fallen. The questions to ask are direct: does the vendor’s modernisation story include retiring the source recorder, physically and contractually? Or does it stop at ingestion? How many decommissioning projects has the vendor completed in the past three years, on which named recorder vendors, with what demonstrable reduction in the customer’s run cost?
Those numbers quickly separate vendors who have done this from vendors who are positioning to.
What the tests have in common
All three tests share the same structural feature: they focus on the edges of the estate. The oldest sources, the strangest formats, the recorders no one wants to touch. The middle of any estate is easy to handle, and demonstrations are invariably built around it — modern Teams capture, recent voice recordings from current-generation vendors, mobile capture from supported partners. Most vendors handle the middle competently.
The edges are where modernisation is either real or it isn’t. The 2012 trader voice recordings that must come out before the recorder finally fails. The disclosure request that lands on a 2017 conversation captured on a platform whose vendor has since sold the business. The DORA examination question about exit plans for a recorder whose sub-processors are undocumented and whose data format is not exportable.
A buyer’s evaluation that focuses on the middle will find vendors that all look broadly similar. One that focuses on the edges will separate the field very quickly.
