Something in the water is on your side.
The web is open water, and something is always circling. We make sure the sharpest thing in it is working for you, finding the weak spots attackers look for before they do.
Enterprise-grade security, priced for the businesses that keep Oahu running.
Small businesses face the same attackers as the big banks, on a fraction of the budget. The big firms price them out, and the local shops bury security in an IT contract they can't leave. Byteshark works differently: fixed packages, clear prices, no lock-in, and plain answers instead of a report you'd need a specialist to read.
Point us where you need us.

We don't hand you a list of maybes. We prove a weakness is real by chaining it into an actual attack, then give you a clear, ranked plan to close it.
Built by someone who does this for real.
Byteshark LLC is an Oahu-based cybersecurity company. Behind it is a practitioner with years spent in security operations, threat hunting, and offensive security, holding a computer science degree with a data-science focus and the Security+, Pentest+, and PORP certifications. Someone who got tired of watching small businesses get priced out or scared into contracts they didn't need.
There's no inflated team here, and no outsourced call center. When you work with Byteshark, you're working directly with the person doing the hunting.
Security isn't a luxury.
Every business deserves to know where its doors are unlocked, whatever its budget.
The threat is the enemy, not you.
We're not here to scare you into a contract. We're here to find the problem and fix it.
Findings without fixes are useless.
Every gap comes with a ranked, plain-language plan to close it.
