A given system's security level is actually a real number between -1.0 and 1.0 (this is known as the system's True Security Level, True-Sec, or Truesec). It is ~~modified and~~ rounded and displayed as the system's security level according to the following rules~~: <ref name="CCP Explorer">[http://www.eveonline.com/ingameboard~~.~~asp?a=topic&threadID=1282632&page=1#4 CCP Explorer forum post]</ref>~~

A given system's security level is actually a real number between -1.0 and 1.0 (this is known as the system's True Security Level, True-Sec, or Truesec). It is rounded and displayed as the system's security level according to the following rules.

* ~~-1.0 to~~ 0.0 ~~= nullsec~~

* If the true security is in between 0.0 and 0.05 the security is rounded up.

* 0.0 to 0.05 = rounded up ~~to lowsec (0~~.~~1 security level)~~

* Otherwise round to precision.

* ~~0.05 to 0.45 = rounded half up (lowsec)~~

* 0.45 to 1.~~0 = rounded half up (highsec)~~

~~For nullsec systems it may be useful to know a system's~~ true security~~, as even though all nullsec systems are displayed as "0.0" in~~ the ~~game, they have true~~ security ~~ratings from -1~~.~~0 up to 0~~.~~0 - and this~~ true security ~~rating affects various game mechanics, such as asteroid belt and rat quality. A system's rounded truesec value~~ is ~~available via the~~ in-game ~~map~~, ~~and the unrounded value~~ can be found ~~through~~ the [~~http~~://community.eveonline.com/community/fansites/toolkit/ official datadump] or ~~any~~ third-party ~~utilities that use~~ the ~~datadump or the data extracted from it~~.

Many security related mechanics use the true security instead of the rounded security status. For example belt rats and mission rewards.

The true security is not visible anywhere in game, instead it can be found in the [https://community.eveonline.com/community/fansites/toolkit/ official datadump] or from [https://esi.tech.ccp.is/latest/#/ ESI API]. Many third party mapping tools such as [http://evemaps.dotlan.net/ Dotlan] also show the true security.

{{expansion past|width=50%|1=In the past, truesec values in the range (0.0, 0.5) were rounded half up, i.e. rounded down to 0.0 because all numbers in that range are below 0.5. This was a bug, because EVE considers all systems above a trusec rating of 0.0 to be lowsec but the game displayed their security level as "0.0". This bug not only caused some confusion (there were sentry guns within apparently nullsec systems) but also some problems in the form of inadvertent security status loss in what seemed like nullsec.
