SiteLock has more than twelve million websites under their product umbrella, and by all accounts has performed well in the space. A couple of years ago they began a campaign to be more consumer facing rather than only enterprise-level.
On their website, Abry says they focus on companies valued at up to $200 million. Abry already owns several web security companies, including StackPath. Neill Feather will now be the CEO of SiteLock, rather than the President — though I'm not sure the relevance of that beyond title.
As far as the operations of the company, I don't believe anything is planning to change from the product side of the business, but rather only some administrative functions.
I don't think this is the type of acquisition that should strategically or otherwise affect much of what SiteLock does. In my view, it's simply a transition of shares. Historically, myself and others would speculate on the relationship between SiteLock and EIG given common investors, and now those elements of the conversation can be put to rest.
