Limmattal IT & Security

Services in detail

Here you can see exactly what I do for each service, how I do it and what you receive at the end. No jargon – and no surprises.

For all security tests

  • I only test with written authorisation and only the systems we have agreed on together.
  • No attacks that disrupt your business (no DoS, no load tests).
  • I access as little data as necessary to prove a problem. I don't download databases.
  • If I find something critical, I call you the same day – without waiting for the report.
  • I store your data encrypted and delete it no later than 90 days after the report.
  • Every report starts with a summary for management, without technical terms. Afterwards I explain everything in a personal meeting.

Managed IT subscription

Fixed monthly fee

I take care of your IT on an ongoing basis so you can take care of your business. You have one fixed contact person: me.

How I work

  1. Free initial meeting, ideally at your office.
  2. Inventory: devices, accounts, licences, backups and security. You receive a short overview.
  3. A clear offer with a fixed monthly fee per workstation.
  4. I set up remote access and document your IT.
  5. Ongoing support: you contact me by e-mail, phone or WhatsApp, and I reply within 24 hours on working days.

What you receive

  • Basic: remote support for your team, Microsoft 365 management, checking updates and backups, staff joining and leaving (accounts, devices, access).
  • Plus: everything in Basic, plus one on-site visit per month and a security check every quarter.
  • Pro: everything in Plus, plus one phishing training per year and a security report for management.
  • Up-to-date documentation of your IT.

What I don't do

  • I don't change anything important without your approval.

What I need from you

  • One contact person in your company.
  • Access to the systems I should look after.

External quick scan

½–1 day

I look at your company from the outside – the way an attacker on the internet would. Without login details and without putting load on your systems.

How I work

  1. I look for publicly visible information: subdomains, technology in use, data in search engines, leaked credentials of your domain.
  2. I check what really belongs to you. If something is unclear, I ask.
  3. I check the open services on your servers (with low load).
  4. I check the configuration: HTTPS certificates, security headers and e-mail protection (SPF, DKIM, DMARC).
  5. I look for outdated software and exposed files (e.g. backups).

What you receive

  • A short report (3–6 pages) with the main risks and concrete measures.
  • My recommendation on whether a full test is worthwhile.

What I don't do

  • I don't exploit vulnerabilities.
  • I don't test logins.
  • No aggressive scans.

What I need from you

  • Your domain(s).
  • Confirmation of which servers and services belong to you.

Hardening review

1–2 days

I check your servers, your Microsoft 365 or your cloud for insecure settings. I only have read access – I don't attack or change anything.

How I work

  1. We agree on which systems I check.
  2. I collect the settings with proven audit tools and compare them with recognised recommendations (CIS Benchmarks).
  3. I check the results by hand so that no false alarms end up in the report.
  4. Microsoft 365: e.g. two-factor login for everyone, number of administrators, forwarding rules, external sharing.
  5. Servers and Active Directory: e.g. password rules, administrator accounts, outdated protocols, updates.

What you receive

  • A list of measures, sorted by priority.
  • For each measure: instructions for implementation and the risk if you do nothing.

What I don't do

  • I don't change settings on my own. Implementation can be ordered separately.

What I need from you

  • An account with read access (or an accompanied session).
  • The list of systems and who manages them.

Web application pentest

2–3 days

I test your web application by hand, the way an attacker would – following the recognised OWASP standard. Automatic scanners alone are not enough.

How I work

  1. I go through the whole application and create an overview: functions, user roles and interfaces.
  2. I check the login: password rules, lockout after failed attempts, password reset, two-factor login.
  3. I check the sessions: cookies, logout, expiry.
  4. The most important part: I check whether one user can see another user's data or get admin rights.
  5. I test the inputs for typical attacks such as XSS and SQL injection, including file uploads.
  6. I check the business logic, e.g. whether steps can be skipped or prices changed.
  7. I confirm every finding a second time and delete all test data at the end.

What you receive

  • A full report: every finding with proof, severity (CVSS) and a concrete fix.
  • An action plan: immediately, within 30 days, within 90 days.
  • A final meeting in which I explain everything to you.
  • On request, a retest at a reduced price.

What I don't do

  • No tests that take your application down (no DoS).
  • No attacks on other customers of your hosting provider.
  • No phishing without an explicit order.
  • No tests in production at peak times without agreement.

What I need from you

  • The address(es) of the application.
  • Two test accounts per role (e.g. 2 normal users and 1 admin).
  • If possible, a test environment (staging).

Retest

½ day

After your fixes, I check whether the vulnerabilities are really fixed.

How I work

  1. You tell me which points you fixed and when.
  2. I repeat exactly the test from the report – plus one or two variants, so that not only the symptom is fixed.
  3. For each point I record: fixed, partly fixed or not fixed.

What you receive

  • An updated report with a status table – as proof for audits, insurers or your customers.

What I don't do

  • I don't look for new vulnerabilities – that would be a new test.

What I need from you

  • The original report and the list of your fixes.

Data recovery & secure deletion

depending on the device

I recover accidentally deleted data and wipe old storage devices so that nothing can be recovered.

How I work

  1. Data recovery: I receive the device with a handover record (serial number, photo, your signature).
  2. I connect it read-only and first make a full copy. I no longer work on the original.
  3. On the copy, I restore partitions and files.
  4. Secure deletion: I wipe according to the NIST SP 800-88 standard, with the right method for HDD, SSD, USB stick or SD card.
  5. Afterwards I check that nothing is readable any more.

What you receive

  • Data recovery: your data on a new device and a list of what could be recovered.
  • If nothing can be recovered, you only pay for the diagnosis.
  • Secure deletion: a deletion certificate per device (model, serial number, method, date, signature).

What I don't do

  • I don't open damaged devices. For physical damage (clicking, drop, water) I recommend a specialised lab.
  • I don't look at the content of your files – I only check whether they open.

What I need from you

  • The device and a description of which data are important.

Secure websites & maintenance

Fixed price

I build fast, simple websites that are secure from the start – like this one.

How I work

  1. We discuss the goal, pages, texts, images and languages.
  2. I make a design proposal (one round of corrections included).
  3. I build a static website: no database and no unnecessary scripts, so very little attack surface.
  4. I create the legal notice and privacy policy under Swiss law. No tracking cookies by default.
  5. I put the website online with HTTPS and strict security settings, also for the e-mails of your domain.
  6. I check the website with independent tests and show you the results.

What you receive

  • A finished website and a report with the test results.
  • All access in your name – the domain belongs to you.
  • On request, maintenance: monthly check and small changes.

What I don't do

  • No online shops and no customer areas (I make a separate offer for those).

What I need from you

  • Your texts and images (or we create them together).
