START WITH YOUR CONCERNS

Security concerns?
Let’s talk, investigate and improve.

“Are our security measures enough?” “Where should we start?” You can get in touch from that first question.

The initial consultation is free and normally online.

DECIDE. BUILD. HAND OVER.

From the first conversation to investigation, configuration changes, code fixes and incident preparation, I do the hands-on work myself.

You can ask about websites, apps, cloud services, internal IT, SaaS, account management and more.

What you can ask about.

These are examples of questions you can bring. You do not need to choose a scope of work or type of engagement first.

  • I am not sure whether our security measures are enough or what to check first.
  • An external developer handles our systems, but I want to understand the situation as a business owner.
  • We need to review staff accounts, sharing settings and access left behind by former employees.
  • I would like someone to check our Google Workspace, Microsoft 365 or cloud settings.
  • I want AI-generated code or systems reviewed and any problems fixed.
  • I need help investigating concerning logs or suspicious behavior.
  • We want to prepare backups, contact procedures and initial incident response steps.
  • I need help responding to a business partner’s security questionnaire.

ONE PERSON. FROM DECISIONS TO CODE.

Decide what matters. Follow it through in code.

Focus the work around your budget, deadlines and business impact. Implement the agreed changes, verify them and leave your team able to carry them forward. I treat that as one job.

From a decision to a pull request.

Authentication, permissions, APIs and dependencies. I review the design and implementation, including AI-generated code, and work through the changes that matter.

Internal IT, cloud services and operations.

I review SaaS such as Google Workspace and Microsoft 365, cloud configuration, account and sharing permissions, logs and operating procedures. Findings and outstanding issues stay visible to the people who take over.

The workplace and infrastructure photographs are illustrative. They do not depict me, my clients or their facilities.

From questions to improvements and preparation.

We discuss your situation and what you need to find out, then agree on useful support. I can take on investigation and implementation as well as advice.

01DISCUSS

Understand the situation.

Work out where to start and what to prioritize within your budget. We discuss your concerns and how you work, then identify the information and next steps you need.

WHAT YOU RECEIVE

A picture of the current situation, priorities and what to check next

02INVESTIGATE

Find out what is happening.

I investigate concerning behavior and settings, then explain the findings and options. This can include logs, account permissions, cloud and SaaS configuration, and AI-generated code.

WHAT YOU RECEIVE

Findings, open questions and proposed actions

03IMPROVE

Make and verify the changes.

I follow through on findings with configuration changes, code fixes and verification. The person making the decisions also does the work and records the reasons for each change.

WHAT YOU RECEIVE

Configuration changes, pull requests, decision notes and test results

04PREPARE

Prepare for incidents and keep improving.

Put backups, contact procedures and initial response steps in place. Ongoing support can include day-to-day questions and reviews of settings and operating procedures.

WHAT YOU RECEIVE

Backup, contact and initial response procedures, plus items to review regularly

Your team should be able to carry the work forward.

I record findings, changes, the reasons behind them and remaining issues. The handover helps the people taking over understand the work and continue it.
