Here's What Our Customers Are Saying About ZetX...

Product Reviews


“I wanted to let you know that both you and your team’s customer support has exceeded any expectations that I may have had. I received a message from your support team after I had a failed report upload. I appreciate your researching my states applicable laws. I will continue working with my investigators and try to educate them on the necessity of tower info in warrants, even if it means having to sit down with the prosecuting attorneys.” – Minnesota


“My DA was impressed when I ran one phone record for her! When it came back in under a
minute she was blown away! I believe the words were, “You just saved me DAYS of plotting towers!” We were able to run the records she had while we were in her office because the system is web based (which is awesome). This took about 15 minutes for all of them by the way. I’m not surprised she called and I’m glad she did. I believe in your product and every cop should have it to help them with their cases. “ – Utah

Court Testimony Reviews


“We had a robbery trial that was scheduled for today. One of our three investigators that attended Sy’s expert class had prepared an extensive PowerPoint presentation—-. He was able to place all five co-defendants at the robbery and other locations related to the robbery. He was hoping to use this case toward his expert certification but once again the defense was presented with the Commonwealth Attorney’s open file policy and ALL FIVE plead guilty. We are talking about 22 years a piece. Not a gift by any means.

My point is that the product works too good in the sense that it is so visually damning to the defendant that they almost always plead guilty when confronted.” -Virginia


“I just wanted to pass on my thanks to ya’ll for all the mapping help ya’ll have given over the last week or so. Just to give you an update on the case we were working on. It started as a missing person with suspicious circumstances and unfortunately turned into a murder investigation. As of 7pm (central time) last night, we had recovered the body of a missing female and put in jail our 4 suspects for 1st Degree Murder, Kidnapping, and Arson. If you would like to see information about the case go to (Tahereh Ghassemi was the victim’s name) which is a local news outlet that has a good article about the case.
Also, ya’ll should be getting a call within a day or two from my captain to begin the process on starting an account for our agency. Again, please pass on to your people our thanks for all your help.” – Louisiana

Training Class Reviews


“Just completed the 40 hour course in Salt Lake City! Looking forward to applying the new knowledge to cases on Monday! Thanks Sy and Keri! This is a great service you’re providing and I can’t wait to show “the guys” what we learned. Your techniques and cell record management services are going to be a “game changer” – Utah


“I just wanted to reach out and thank you for all your hard work on organizing the cell phone training last week. I got a lot of positive feedback from the detectives that took the course and they were all very pleased with all that they learned. I think this was a good step for our agency and hopefully now that they see how important cell phone records are to investigations, that they will all go back to their command staff and push for Trax/Linx. Sy did a tremendous job relaying his knowledge and expertise to the class and he was well received. Again I just wanted thank you and your staff for your hard work.” – Arizona

Cell phone mapping scientific standards vary by state. Do you know your states standards? For instance, Texas uses Rule 702 of the Federal Rules of Evidence and New York uses Frye Standards.  They are trial motions that aim to preclude evidence based on their scientific validity. Consequently, scientific motions like, the Daubert Standard,  can result in loss of evidence. For that reason, understanding best practices of cell phone mapping is important for every investigator and attorney. ZetX subject matter experts testify to Scientific Challenges throughout the United States.  Most states follow the same guidelines, however, there are differences based on the judges opinion at the time of trial.

Los Angeles, California

More importantly, ZetX uses scientific practices like drive testing, and as a result, overcome scientific motions on a consistent basis. The standards we use at ZetX provide excellent results in trial because we meet and testify to the toughest scientific thresholds. The most noteworthy being, extended testing of our theories and techniques and well documented known error rates within the cellular networks.  You can learn more about this topic by attending a ZetX 40 Hour Basic Course. Thereafter, you are eligible to attend the Subject Matter Expert Course and represent your agency.

Miami, Florida

If you have a case that requires review of cell phone records, and need some help,  just contact us. Cellular investigations can be a tremendous undertaking, for that reason, your case will be reviewed by a ZetX Subject Matter Expert who will determine how we can assist you.  We have helped agencies big and small, from state to federal, we’ve reviewed cases for prosecution and defense, and even work on civil cases. You are not alone in your pursuit for justice. Sometimes, it just take a little tenacity and hard work.

A potentially big ruling came out of the courtroom of Judge Lucy Koh yesterday, in which she affirmed a magistrate judge’s decision to tell the government to get a warrant if it wants to obtain historical location info about certain “target” mobile phones (officially known as “Cell Site Location Info” — or CSLI).
