Archive sources and document availability
Check the primary sources behind the Crestcon archive, what each establishes, the surviving materials and the historical files still unavailable.
This register explains the evidence used by the historical archive. It records the difference between a scheduled session, a later report, a speaker's own material and a reference to a file that we have not recovered. The checks below were completed on 2 November 2026.
The site is an independent publication by Serallo Domains Ltd. Links to organisers and speakers help readers inspect sources; they do not imply approval, partnership or ownership of the linked work.
How to interpret an archive record
| Label | Meaning | What it does not establish |
|---|---|---|
| Programme record | A contemporary source schedules a session | That it ran unchanged, or that slides survive |
| Retrospective report | A source written after the event describes what happened | A complete transcript or confirmation of every session |
| Author record | A speaker describes their own work | Independent verification of every technical claim |
| Surviving deck | A readable presentation file is available | That it is identical to an unrecovered historical copy |
| Related material | A relevant resource from another occasion | That it was presented at this event |
| Bibliographic reference | A source cites a title or address | Access to the cited file's contents |
We use these distinctions throughout the 2013, 2018 and 2019 records. A source's publication date, an archive's capture date and the date of our new article are separate fields of evidence.
Historical event sources
2013 homepage
Open the archived homepage captured on 14 June 2013.
Publisher: the historical conference site. Evidence: event notice, venue, two stream descriptions and the agenda links. Limit: the capture does not contain either full agenda. The 2013 record reports only what that surviving material supports.
March 2018 organiser bulletin
Publisher: CREST. Evidence: the advertised technical programme. Limit: a pre-event listing, not a delivery transcript. See the 2018 record.
Contemporary 2018 exhibitor announcement
Read 44CON's event announcement.
Publisher: 44CON, writing as an exhibitor. Evidence: contemporary confirmation of the advertised date, venue and BCS stream. Limit: the URL contains an old year; the actual page heading and body identify the 2018 event.
January 2019 organiser bulletin
Publisher: CREST. Evidence: the event notice, link to /presentations-2019/, stream structure and historical sponsorship-brochure address. Limit: former ticket and sponsorship arrangements are not current offers.
Detailed 2019 programme
Open the programme special issue.
Publisher: CREST. Evidence: scheduled speakers and timings. Limit: programme, not proceedings. Our 2019 page provides an original index rather than copying its abstracts and biographies.
May 2019 organiser follow-up
Publisher: CREST. Evidence: a retrospective report and an explicit reference to the digital brochure. Limit: its description of slides and video availability is historical; each resource still needs checking individually.
Surviving presentation and project material
| Source | What we checked | Classification |
|---|---|---|
| Netscylla's 2018 red-teaming PDF | Genuine PDF, named presenters and matching subject | Surviving deck; original local-file identity unproven |
| Rewanth Tammana's CRESTCon page | Author record and linked project | Author account; date discrepancy explained on our year page |
| Browser-extension repository | Public project and documentation | Code resource, not slides |
| Sheepl repository | Public user-simulation project | Code resource |
| April 2019 OWASP Sheepl deck | Genuine PDF identifying a later presentation | Related material, not authenticated CRESTCon slides |
A link described as available was readable at the check date. That is not a promise that an external publisher will keep it online. We link to material at its source and do not assume that public access grants permission to republish it.
Documents that have not been recovered
The following addresses are recorded as historical identifiers. They are deliberately displayed as filenames rather than presented as working downloads.
| Historical address | Evidence of its former purpose | Present treatment |
|---|---|---|
/stream1.pdf |
Linked from the 2013 homepage beside the first stream | Missing-document response; context on the 2013 technical stream |
/stream2.pdf |
Linked beside the second stream | Missing-document response; context on the 2013 management stream |
/wp-content/uploads/2019/03/DigitalCRESTConbrochure2019.pdf |

Cited in an IBM report | Missing-document response; bibliographic record below |
Martin Borrett reference
IBM's 2019 report on business and artificial intelligence cites Martin Borrett's “Security in the Cognitive Era – Bringing the Power of Cognitive Security to The Security Analyst”, dated 28 April 2017. The citation appears in the chapter 7 notes, on printed page 60, and gives the historical MartinBorrett.pdf address.
This establishes a bibliographic trail. We have not recovered the cited slides and do not reconstruct their arguments from the title. The report remains a useful source for locating the reference, rather than a substitute slide deck.
How corrections are handled
Useful correction evidence includes a speaker's own dated page, a complete programme, a verifiable recording or an original document with a clear source. Tell us exactly which entry it affects and what the evidence changes. If a file is proposed for republication, its rights and provenance also need to be clear.
Use the contact page to send a source address or explain what you hold. Do not send private attendee records, credentials or incident evidence. We can amend an inaccurate entry, add an authenticated resource or retain a documented uncertainty; a plausible recollection alone is not enough to invent a missing programme.
For practical reading, the research guide and conference-learning notes help record a claim, the evidence actually seen and the questions that remain.
