There is not a single unit on the market that is 100% safe during a direct lightning strike, so make sure you have a backup

No lightning strike, etc, the UPS just failed to come back on when the power bumped so my filter pumps stopped working.

I had a storm last year that crippled about $3000 worth of equipment when a bolt of lightning struck very close

When the batteries on my APC BR1500G failed the self test after 5 years I figured this would have been a good time to get a rack mount UPS for my server rack
