Glow is WordPress maintenance and management software for agencies: updates, uptime and SSL monitoring, backups, vulnerability scanning, client reporting and support tickets, for every site an agency looks after, in one dashboard.
A vulnerability is published most weeks and the first question is the same: which of my sites are exposed? Answering that across forty sites means opening forty dashboards, so it does not get answered until something breaks. Connected to Glow it is one question with one answer, and the follow-up (update those, safely) happens in the same conversation.
What you can ask: which sites run a plugin below a given version; what needs updating on a particular site; which sites a newly published vulnerability affects; which went down this month and which certificates expire soon; which have no recent backup or no scheduled report; and which clients are over their monthly time allowance.
What it can change, each behind its own permission, granted deliberately and none of them required: run updates, where plugins go through Safe Updates with a backup and screenshot first, a check afterwards and a rollback if needed, while themes and WordPress core are not reversible, which the tool says plainly before running one; turn uptime monitoring on or off for a website; and log work against a website and set its monthly time allowance.
What it can never do: delete a website, a backup or a client, or deactivate a plugin, a theme or anything on a client's website. Those are not exposed to assistants at all.
A connection sees exactly what the person who authorised it sees, including any per-website restrictions, and never receives passwords, connection keys or website content. Every request is logged, and a connection can be ended at any time.
For WordPress agencies, freelancers and reseller accounts looking after many client sites.
