Just do it in moderation.

LONDON (Rixstep) — London/Stockholm/Mediterranean-based Rixstep today announce SPX 2.4 and SPX Nighttime 2.4, important ACP updates for macOS 10.14 'Mojave'. SPX, released in 2003, is the first industrial-strength file shredder for Apple's desktop OS, and SPX Nighttime is its disk-shredding counterpart. SPX and SPX Nighttime secure your disks in a way that's bettered only by outright physical destruction.

London — Independent development team, Rixstep, today are proud to announce the release and immediate availability of SPX 2.4 and SPX Nighttime 2.4, important ACP updates for macOS 10.14 'Mojave'.

The SPX engine, which is capable of following the complete 35-step Gutmann regimen, and then some, offers unparalleled security for the Macs of today.

Both SPX 2.4 and SPX Nighttime 2.4 have now been updated for macOS 10.14 Mojave, and have now been distributed to registered users.

Back in the Last Millennium...

Rixstep's sister company Radsoft had the first professional shredders for Windows.

The original SPX got a writeup in 'Windows Magazine' at the time. It was a response to a plea for proper shredding software for Windows, where the market had been saturated overnight by less-than-professional offerings.

Rixstep followed by being first on Apple's OS X, already back in 2003.

Too many indie software houses were offering shredding schemes intended for use on volatile random access memory only. As Peter Gutmann pointed out at the time, these supposed 'shredding standards', made available by the NSA, were hardly going to reveal all of the agency's secrets.

Dr Gutmann's shredding method, incorporating 35 sovereign steps, all of which must be forcibly flushed to disk, was the result of his analysis of prevalent analog methods used in secondary storage.

Things have changed since the release of that paper, but, as Dr Gutmann points out in a later paper, the security promised by products incorporating the new 'solid state' technology (SSD) have not yet convincingly proven their merit.

The file shredder SPX 2.4 offers 39-step 'Gutmann' shredding. The disk shredder SPX Nighttime 2.4 offers both a simpler disk shred and the full 'Gutmann' shred (the 'weekend' option). The recommendation is to use the full 'Gutmann' in moderation, as SSDs can eventually deteriorate, and stick to SPX Nighttime for the most part.

SPX is fast, and easy to use. Simply fire up the app, drop on the files you want to shred, and click 'Shred'.

Above you can see SPX performing a complete 39-step shred of eight files of 100,000,000 bytes each, completing the task in just one minute.

Device Requirements

  • macOS Mojave 10.14 (earlier versions also available)
  • Backward compatible to 10.7.5
  • 64-bit processor
  • 81,629 bytes (SPX) 85,782 bytes (SPX Nighttime)

Pricing and Availability

SPX 2.4 and SPX Nighttime are part of the Xfile System along with over 20+ other file management utilities, priced at only $59.00 USD (or an equivalent amount in other currencies) and available worldwide exclusively through the Rixstep website and associated payment processors. Of course they're also available as part of the complete $99.00 ACP.
