Security Services

San Diego

32 businesses listed. How we order them.

San Diego has 32 security service listings in this directory, and every one of them has a phone number attached. Twenty-seven also list a website, so calling or clicking through to check hours, coverage areas, or services rarely hits a dead end. Zip codes 92101 and 92111 each carry 6 entries, giving you a decent set of options if you're in downtown or the Linda Vista and Serra Mesa area. 92108 and 92123 follow with 4 apiece, while zips like 92103 and 92113 have just one listing each, so there's less to compare there before you pick up the phone.

None of these listings carry a Sponsored tag at the moment, since paid placement hasn't been switched on for this category in San Diego, so the order you see is simply the sequence in which companies were added, not a ranking. If you manage one of these security firms and notice your website field is empty or your number's off, you can claim the listing and fill in the missing details yourself. That's especially useful in the lighter zips, where a searcher nearby might only find one or two names to try.
