Most businesses find out their IT isn’t resilient only after something breaks. By then, the cost is already moving: downtime that can’t be invoiced, clients questioning reliability, and a scramble to recover systems that should have been protected in the first place. This checklist is built for business owners and IT leaders at companies with 20 to 250 employees. Take it first. The research behind it follows.
- 88% of SMB breaches now involve ransomware, more than double the 39% rate at large enterprises. Small businesses aren’t just targeted as often; they’re targeted differently.
- AI-generated phishing is reshaping the entry point: these messages now convert at roughly 4.5 times the rate of traditional phishing, and close to half of SMBs report encountering an AI-generated phishing attempt in the past year.
- Businesses with a documented incident response plan save an average of $232,000 per breach compared to those improvising a response mid-incident. It’s one of the cheapest resilience investments on this checklist.
- Having a backup and having a tested, working backup are two different things. That gap, more than any single tool, is where most recovery plans quietly fail.
The Cybersecurity Resilience Checklist
Fifteen questions, four categories, two minutes. This won’t tell you everything is fine. It will tell you exactly where to look. Check off what’s already true at your business, and watch the score update as you go.

The 2025 Verizon Data Breach Investigations Report, drawn from more than 22,000 real-world security incidents, found that 88% of breaches at small and mid-sized businesses involved ransomware, compared with just 39% at large enterprises. That gap is the story: attackers aren’t only hitting small businesses more often, they’re hitting them with the attack type least likely to be survivable without a tested recovery plan already in place.
The entry point is shifting too. Traditional phishing relied on obvious tells: bad grammar, mismatched logos, a sender address that didn’t quite match. AI-generated phishing emails now achieve roughly a 54% click-through rate compared to 12% for human-written phishing, a 4.5-times jump in effectiveness, and nearly half of SMBs report running into an AI-generated phishing attempt in the past year. A team trained on last decade’s red flags is being tested against this decade’s attacks.
None of this makes a breach inevitable. It does mean the gaps that used to be low priority, an untested backup, a missing incident response plan, employee training that stopped at the basics, now carry more weight than they used to. Sophos puts the median ransomware demand at $1.32 million and the mean total recovery cost at $1.53 million, and the average business is down for 24 days after an attack. For a company in the 20 to 250 employee range, three and a half weeks without normal operations is a serious event under the best circumstances.
The five gaps most SMBs carry right now
These are the vulnerabilities that show up most consistently in businesses this size, and they map directly onto the checklist above.
What “resilient” actually means at your company size
Resilience is the ability to keep running when something goes wrong, and to get back to normal quickly when it does. For a 50-person business, that comes down to three things: knowing your data is backed up and genuinely recoverable, knowing your team can recognize the attack patterns actually being used against businesses your size right now, and knowing someone is watching your systems so you don’t have to. Roughly 66% of SMBs still don’t have a documented incident response plan, which is often the single fastest gap to close.
What a managed IT partner actually does about this
A managed IT partner doesn’t just respond to problems. They own the posture that prevents them: continuous monitoring so threats are caught before they become incidents, automated patching so systems don’t fall behind, backup management with regular recovery testing, security awareness training that covers AI-era phishing rather than only the old red flags, and a team that answers the phone when something looks wrong. Recovery is only part of resilience. Protection and ongoing management complete the picture.
For businesses in the 20 to 250 employee range, that combination is what resilience looks like in practice: a capable, responsive partner who treats each engagement like it’s the only one on the board, not a perfect, unbreakable defense that doesn’t exist for any business at any size.
The checklist is a starting point. The assessment is the map.
