Traditional models of security are generally built according to an architecture that we could compare to a castle surrounded by moats, where a distinction is made between the interior of trust and the exterior of which we must be wary.
However, these models are no longer adequate to deal with today’s cybersecurity problems. Not only can attackers manage to infiltrate this internal zone of trust and cause significant damage, but the border between the “outside” and “inside” is becoming less and less relevant to describe information systems. For example, with the rapid acceleration towards the Cloud, there has been a real shift in resources on the Internet causing a fairly large area of exposure.
We are thus witnessing a period of transition: from a binary digital world, with a distinction between the inside and the outside, to a much more complex world, sometimes called “borderless,” where threats are protean and attackers are everywhere.
This is why today, the same level of trust can no longer be attributed to all the active resources of an enterprise: a more modern model is needed, notably with “Zero Trust,” in which new solutions have appeared: ZTNAs (Zero Trust Network Access).
ZTNA have experienced a real boom in 2020, with the global pandemic and the resulting increase in technical resources, such as remote work, BYOPC/BYOD, etc.
TEHTRIS ZTR, or “Zero Trust Response,” is the first and only ZTNA offered worldwide that comes with automatic incident response options and highly advanced low-level detection, without the need to add plenty of extra tools that would increase costs and cause a substantial loss of time.
