Security Update – PHP Vulnerability

We are aware of the recent critical PHP security vulnerabilities highlighted by the National Cyber Security Centre (NCSC) on 21st October 2026.

We would like to reassure customers that our main platforms, 4Matrix Cloud and 4Matrix Fusion, do not use PHP and are therefore not directly affected by these vulnerabilities.

PHP is used within some of our supporting systems, including our customer support ticketing and billing systems. Our desktop application also communicates with our sales system for licence verification. These systems do not store customers' payment details or sensitive information as part of the licence verification process.

We have been in contact with our hosting provider, Krystal, who has confirmed that the necessary security fixes have been applied to address the reported vulnerabilities.

No action is required from our customers in relation to this advisory.

We take the security of our systems and customer information seriously and will continue to monitor security developments and work with our hosting provider to maintain appropriate protections.

Can 4Matrix analyse termly assessment grades as well as results data?

Yes - You can import any number and type of data series into 4Matrix.

A series is a snapshot of performance - a 'Y11 Autumn 1' series may refer to teacher assessments that were taken before Autumn half term.

Over the course of a year, 4Matrix can be used to analyse, diagnose, track, forecast and report on the progress of pupils from years 7 to 14. 

Greater emphasis is placed on KS4 however - the significance of this is that it is this information that will largely influence an inspection judgement. 

Progress is monitored by entering series of most-likely grades into 4Matrix, either once or twice a term.

For a new group of Year 11 pupils, a typical data cycle might include:

  1. 1Y10 mock exam results - this will provide the first series for the new cohort of Y11
  2. Autumn Term - most likely grades entered twice during the term
  3. Target grades
  4. Spring Term - most likely grades entered twice during the term
  5. Summer Term - most likely grades entered
  6. Actual exam results available in August

All of these data points can be imported into 4Matrix as a Series. There is no limit to how many series you can import. A similar cycle would take place for year 10.

This will provide an analytical record of Y11 performance using a ‘point analysis’ technique, i.e. several series of data about estimated grades collected twice per term, forming a record of movement over an academic year. Here are just some examples:

  • The Series Analysis tool will show the differences between any series for a selected cohort of pupils
  • The Series Comparison tool will show the movement of grades towards the target grades for a specific subject area in a highly graphical format
  • The Subject Analysis tool will show the movement of grades towards the target grades for a specific subject area using tables and colour-coding
  • The Progress Graph tool will show trajectories for every pupil based on national chances tables, against which their attainment and progress can be plotted
