Cybersecurity

Find, Close and Watch Every Gap.

Overview

We find the gaps attackers use, close them in order and watch for the next one.

The work covers identity, applications, cloud, industrial systems, AI and cryptography, with engineers from KONG GROUP, where cryptographic software is built and tested.

How to Start

What Happens Next

  1. Pre-Consulting Session

    A free 30-minute online pre-consulting session: we go through your goals, systems and constraints.

  2. Readiness Review

    In a free 48-hour Readiness Review, a Principal Architect checks your project against What we need before we start and recommends the track that fits.

  3. Choosing the Track

    Scope-ready projects receive a binding proposal within 3 to 5 business days. Concept-stage projects start with Discovery and Design. A live system that is failing, undocumented or needs integration starts with the Live System Review of 1 to 2 weeks. Discovery and Design and the Live System Review each have a fixed fee, quoted in the proposal.

  4. Delivery in Five Stages

    Mobilisation, sprints with live demonstrations, integration and hardening, acceptance and go-live, then managed services. After launch comes a warranty period, then optional support and maintenance.

The quickest way in is the Security and Cryptography Review package, one of our rapid engagement packages.

Where to Start

Questions and Answers

Where should we start with cybersecurity?

Start with the systems that would hurt most if attacked. Usually they hold customer or payment data, move money or keep the business running. A focused assessment of them shows the weaknesses that matter and gives you a ranked plan. If you use AI agents or hold data that must stay secret for years, AI security or post-quantum cryptography is the natural first step.

What drives the cost of security work?

The main drivers are the number and size of the systems in scope and how deep the work must go. Cost also depends on whether we fix what we find, the number of sites or agents, and the evidence your auditors need. We confirm the scope first, then send a proposal with the method and the price.

What do you need from us?

A named owner for each system in scope, the access and test windows we need, and a person who can decide on risk. You also decide what may be changed and when. We bring the method, the evidence and the people who do the work.

What happens if we have a security incident?

Follow your response plan and call the contacts it names. If we support your systems, your XSIS contact is one of them. We work with your team to contain the incident, keep the evidence, restore service and find the cause. Afterwards you receive a written review of what happened and the changes that prevent a repeat.
