The long view, in 8-K filings
An 8-K is filed within four business days of an event, so this counts filings made because something happened.
Every month since 2008. The last point is the current month and is still
filling, so it always looks lower than it will be.

Who is hiring for it
A sample of the open roles naming this phrase. An employer paying a salary
against something is the least ambiguous demand signal there is, and every row links to the
posting so the claim can be checked rather than believed. The total above is the whole US
market; these are the ones we hold the posting for.
How it actually arrives
An 8-K's meaning is in its item number, not its text. These are the items the filings
containing this phrase were filed under. The first group is something that happened to the
company. The second is the phrase turning up in the ordinary course of reporting, most often in
an earnings release, which is a very different thing and is usually the larger number.
| Filed because something happened |
Companies |
| Other material event Item 8.01 | 693 |
| Director or officer departure Item 5.02 | 372 |
| Change of accountant Item 4.01 | 35 |
| Delisting or listing rule failure Item 3.01 | 32 |
| Bankruptcy or receivership Item 1.03 | 18 |
| Material impairment Item 2.06 | 4 |
| Financial statements no longer reliable Item 4.02 | 2 |
| Mentioned in routine reporting |
Companies |
| Financial statements and exhibits Item 9.01 | 1789 |
| Entry into a material agreement Item 1.01 | 1641 |
| Regulation FD disclosure Item 7.01 | 967 |
| Completion of an acquisition Item 2.01 | 303 |
| Results of operations, the earnings release Item 2.02 | 172 |
| Shareholder vote Item 5.07 | 40 |
This is why a headline count on its own overstates the case.
Where the routine number dominates, the phrase is being tracked as language rather than as
events.
Which industries file it

survey.

What it obligates
Our corpus holds 121 controls across
90 frameworks whose text speaks to this. Not a judgement:
these controls say so, and each is one lookup from its source document. Ordered by how much each
framework has to say about it, so the one that will cost you the most work is first. Every name
opens that framework in the corpus.
What an auditor will ask you to produce
The artefacts named on those controls, most frequently cited first.
- Breach register
- Encryption + pseudonymisation evidence
- Internal breach register
- Breach detection + SIEM/DLP/EDR/insider + records + per incident + audit trail
- Configuration / tooling output demonstrating the safeguard
- Records showing the safeguard is operating (logs, reports, reviews)
- Affected data subject notification
- Breach notification SLA
How it usually fails
Recorded when each control was verified against its source. This is where programmes
that think they are covered turn out not to be.
- No encryption
- No data subject breach notification
- No processor contracts
- Breach detection passive (manual reports only)
- Subject notification skipped (high-risk underestimated)
- Safeguard implemented for some assets but not all in scope

Data Breach in 10-K and 10-Q filings, by month.
The marked line is the first month any public company in our record used the phrase; everything left of it is nobody writing it down.
What this actually means
- Why now
- 11 public companies wrote this into an 8-K in the last seven days, 45% fewer than the seven before. That is not sentiment or a survey. It is a count of companies choosing to put a phrase into a document they are legally accountable for.
- Who already cares
- 796 open US roles name this work today, which suggests increased attention to it beyond what any filing says. A job advertisement clears a budget holder and a filing clears legal, so the two answer to different people. We have not measured which moves first, only that both are moving.
- What comes into scope
- Once the phrase is on the record it maps to obligations within ISO 27001:2013, ISO 27001:2022, HIPAA Security Rule. 370 controls behind those, and the difference between asserting them and evidencing them is the whole of the work.
- Who is quietly ahead
- Anyone already running ISO 27001:2013 has done 584 of the controls that carry ISO 27701:2019 too. Same evidence, second standard. Most organisations run those as two programmes with two budgets because nobody told them the mapping existed.
- Who is exposed
- 80 companies disclosed this for the first time in the last ninety days, out of 1815 in total. A first mention is a company deciding it can no longer not say it. Whoever has not yet is either genuinely unaffected or has not looked, and nothing here distinguishes the two.
What this obligates
The instruments in our corpus that govern this disclosure, and how many controls sit
behind each. This is not a filing count. It is what applies once a company has written the
phrase down.
8 frameworks, 370 controls between them.
What closing it also moves
The same controls appear in other frameworks through mappings held in our corpus. Work
done here is already progress there. This is the part that is not in EDGAR and not in any public
dataset: it comes from mappings built and verified by hand, control by control.

Tell me when Data Breach files something new
One email when a public company newly discloses this, naming the company and what our corpus says it puts in scope. Nothing else, and one click to stop.
Where this comes from
The left half is public record: SEC full-text search over 8-K filings, counted across a
7 day window against the equivalent window before it. You can check
every row.
The right half is ours: 723 frameworks and
20,473 controls, 531 of those frameworks verified against
their source documents, with the auditor evidence and common failure modes recorded control by
control. Controls appear here because their own text names this term.
