Blacktip: could your team spot a real one?

Whitetip tells you if a message is a scam. Blacktip asks the harder question. AI-driven phishing simulations tuned to current, industry-specific attacks, informed (PII-stripped) by what Whitetip sees in the wild. Fail a phish and the training that follows is made for Hawaii by Hawaii, with local actors, not the generic corporate video everyone clicks through half-asleep.

For a business facing an insurance questionnaire

Cyber insurance readiness

Insurers now ask hard questions before they'll cover you: multi-factor login, tested backups, endpoint protection, and more. We translate the questionnaire, find the gaps, and get you answer-ready, so you qualify for coverage and better rates.

Questions

Common questions.

Do I need to be technical to use any of this?

No. Whitetip gives you a plain-language verdict on a suspicious message, and every report we write is meant to be read by a business owner, not a security engineer. If a finding matters, we tell you what it means and what to do about it.

How much does small-business cybersecurity cost?

Whitetip is free for individuals and $29/mo for a team of up to 20. Cyber insurance readiness starts at $1,500 as a one-time assessment. Web app penetration testing is by application while Mako is in development. No retainers, no lock-in.

What's the difference between a vulnerability scan and a penetration test?

A scan flags things that might be vulnerable. A penetration test proves whether they actually are, by chaining weaknesses into a real attack the way an intruder would. We focus on proof, then hand you a ranked plan to fix what's real.

Do you lock me into a monthly contract?

No. Most local shops bundle security into an ongoing IT contract. We don't. You buy the specific work you need, once, with a clear price up front.

Are you actually local to Hawaii?

Yes. Byteshark LLC is based on Oahu and works with businesses across Hawaii, plus remote clients for the tools and research that don't depend on location.
