TEHTRIS EDR has several functions to perform automated remediation, based on predefined parameters, which allows to fight effectively 24/7 against unknown threats, without the risk of having to depend on a human team that might be missing elements.

TEHTRIS EDR proposes to search for more than 11,000 CVE vulnerabilities, which can sometimes uncover totally invisible things, such as machines that are vulnerable because of an old Java, Adobe Reader, or Flash engine, forgotten or installed in “legacy” mode. You can thus deploy TEHTRIS EDR to audit your IT assets, without consuming excessive resources, and thus have the ability to ensure the compliance of your IT assets: patch management policy, risk aversion criteria, etc.

TEHTRIS EDR has a kernel driver that allows it to modify the behavior of the operating system, so as not to leave the possibility of unwanted execution. Even ransomware that is unknown, signed, stealthy, malicious, could not execute if you decide to configure these policies.

TEHTRIS EDR has several protections against ransomware: blacklists in our CTI database that enrich the choices of EDRs, application security policies to authorize only what you want, Honeytokens type concepts with fake files that a ransomware will want to destroy while being detected (file type decoy), and many mechanisms based on behavioral: attack of certain points of the hard drive, etc…

TEHTRIS EDR has several means to combat lateral attacks, including the ability to process local logs in the operating system to detect if activity is being attempted remotely. It is a true tactical SIEM, local, capable of knowing whether a session is interactive or not, remote or not, in order to be able to track such attacks.

TEHTRIS EDR embeds a highly sophisticated analysis engine capable of differentiating between an illegitimate product and an illegitimate one, in PowerShell terms, by analyzing the code executed on the fly so as not to miss one of the many modern, stealthy attacks associated with it.

TEHTRIS EDR provides its own protection through layers that are directly in the Windows kernel, via a low-level driver, so that it cannot be uninstalled outside of an authorized centralized decision. It is not possible to remove the agent.

The analysis of malicious URL links with C&C lists, etc. is mainly conducted by the TEHTRIS EPP product. In Hunting mode, we can nevertheless do targeted searches for these threats with TEHTRIS EDR.

TEHTRIS EDR continues to operate with its security policy already loaded, when it goes offline. It then stores the events that it will report upon reconnection to its Endpoint appliance. Of course, throughout this phase, the risk of intrusion, without a network connection, seems to be reduced, since TEHTRIS EDR can also contain USB attacks for example.

TEHTRIS EDR may request the TEHTRIS Cyber Threat Intelligence module of TEHTRIS XDR Platform, to perform sandbox scans, offline antivirus scans, neural network engine scans, or malware knowledge base searches.

TEHTRIS has many elements related to artificial intelligence and automatisms associated with the Cyber world. In Machine Learning mode, TEHTRIS EDR learns all the executions in your infrastructure, in order to detect anomalies, including also the persistence points used by hackers to survive a reboot or reconnection. In Deep Learning mode, TEHTRIS EDR has a compact neural network-based engine that can tell if software is malicious or not. This engine is also used in TEHTRIS Cyber Threat Intelligence. The latter is the first French product accepted by Google on its free service VirusTotal, where a public and non-commercial version is constantly running in search of unknown malware.

TEHTRIS EDR natively uploads at-risk files back to its infrastructure so that the payload can be detonated in a Sandbox environment. Robots plan and control the execution, analyze the results, and return the right information back to the EDRs on their own, so they can make a decision.

To put it simply, EPPs are the official tools, being antivirus next-generation and protecting the OS against known attacks. That’s the real system shield. EDRs are the tools used to detect unknown threats and handling security issues remotely with a range of incident response functions. TEHTRIS believes that the difference will become blurred and that EDR and EPP products will become one tool, through a necessary technological convergence. The existence of an EDR market was only possible because they filled technical gaps on the EPP side. In a future that is already beginning, companies will choose one product, an Endpoint protection solution, combining EDR and EPP logic of the same brand, to avoid agents issues. TEHTRIS EPP and TEHTRIS EDR are already available for this purpose.

We must choose the criteria that allow neutralization by software robots. It’s a risky action, that some EDR products don’t want to offer, for fear of breaking everything. But the day an unknown ransomware comes in, these EDRs which are only used for response and analysis, will be able to say that they have understood why the company is being destroyed. No safety at all. This is not our philosophy and we prefer to offer automatic neutralization, carefully and properly configured. Depending on the aspect of the unknown software, you will be able to decide whether to let it go or not: behavior, sandbox results, antivirus results, antivirus databases results, etc.

For mobiles, we offer another range of products, called Mobile Threat Defense, different from TEHTRIS EDR. This is TEHTRIS MTD.

We collect metadata in a way that is compatible with the GDPR, and we will be able to exchange on these elements if you wish.

If your EPP agent plays at killing security software protecting your infrastructure, there might be a problem with the EPP settings or even the product. Currently, for all customers who do not have TEHTRIS EPP, and who have been using TEHTRIS EDR since 2014, we have encountered a total of zero conflict issues with other EPP brands.

A TEHTRIS EDR agent can be instructed that its host might only accept outbound network flow to its management appliances, so that a SOC can quietly study its host, without taking the risk of lateral movement or internal exploration.

TEHTRIS EDR runs on Linux, Apple MacOS, and Windows.

TEHTRIS EDR collects and analyzes security logs from workstations, providing a so-called tactical SIEM capability, in order to keep very interesting events for cybersecurity analysts.

TEHTRIS EDR uses less than 1% on average on the CPU, and less than 100Mo to 200Mo in RAM, depending on the settings you want to setup: loading the neural network in memory or not, etc….

TEHTRIS EDR supports obsolete Windows OSes, such as Windows XP and Windows 2003, which we very often encounter, especially in industrial computing environments (EO, ICS, SCADA) that sometimes need to keep these systems for decades, regarding the cost price of a plant and the related specific equipment.

TEHTRIS EDR has been tested and deployed by some of our customers in industrial environments on Windows boxes that were not advertised as supporting it, by the manufacturers. These customers could no longer imagine not having antivirus (not enough RAM, too old, etc) or no EDR (light and powerful but not officially supported by the OT manufacturer). So, they made agreements with the manufacturers, and they conducted some tests alone, with the help of TEHTRIS in background. For example, we are in factories with equipment from different brands, like Siemens (Simatic, Simotion, WinCC, TIA…), etc.

TEHTRIS EDR can prohibit the use of external storage, or even set it to read-only to prevent deliberate or inadvertent exfiltration. TEHTRIS logs all traces of connected USB devices to provide traceability regarding these threats.
