Expel has transformed MDR workflows and now streamlines phishing response and SOC 2 audits
Some of the best features Expel offers is the ease of use. Ease of use is top of mind. It also provides an opportunity for me to replace my SOC. Not necessarily replace my SOC because I utilize contractors on an as-needed basis, but it allows me to stay lean. I do get 24/7 monitoring, although they recently shortened up on the 24/7 monitoring offering. It also allows me to augment the existing SOC that I have for larger companies or larger enterprises that rely on me for that. It then extends the use of the tools I already have, as I mentioned with SentinelOne. Octa is another that comes to mind, and then for larger organizations that use CrowdStrike.
