Quantitative Security & Risk Analysis

From blind spots to clear decisions.

Assess whether you can withstand cyberattacks, quantify your cyber risk and identify your next priority.

See what we can do for you

Plenty of tools and reports. Too few answers.

  • Compliance is green. Do your controls actually work?

  • What could a cyber incident cost — and which investment is worth it?

  • Where would your business grind to a halt during a cyberattack?

  • You invest in security. Can you prove you’re becoming more resilient?

Avant Cyber connects security data, threats and business consequences, so you can target investments and adjust your security approach.

Explore cybersecurity from your perspective.

Understand your financial cyber risk

What financial consequences could cyber incidents have, and how much risk can your organisation absorb? Estimates of potential losses and their likelihood help you decide where controls are needed and which risks you can consciously accept.

Services

Assess whether you can recover in time

Your recovery plan needs to match the disruption your business can tolerate. We assess dependencies, recovery sequence and available test evidence. You see which recovery times are supported and where further testing is needed.

Services

Compare your security investments

Introduce new controls, renew a contract or continue with your current approach: what does each choice deliver, and what risk remains? Compare costs and expected risk reduction across your options, taking existing controls into account.

Services

Decide which risk to accept

Not every cyber risk calls for a new investment. You need to weigh the cost of additional controls, how much risk they reduce and the consequences your organisation can absorb. This clarifies which remaining risks require an explicit acceptance decision.

Your security question deserves a specialist.

Founder of Avant Cyber

My background combines cybersecurity and data analysis with business administration and economics. At financial institutions, I worked in security operations, cyber risk analysis and the design of measurement frameworks. This combination helps me assess technical findings and understand their implications for business decisions.

From technology to business consequences.

We connect threats, control performance and business processes. This makes the same security question meaningful to both your team and the board.

We examine what is behind the figures.

We check what your data measures, what is missing and which conclusions you can draw. This shows whether a changed score also says something about how your controls perform.

A result you can use.

We also develop and implement measurement models, dashboards and reporting processes. Your team gets guidance on use and maintenance. If you want us to, we agree on what Avant Cyber will continue to maintain.

Independent of security product sales.

We do not sell security products. We are paid for measurement, analysis and the development of security information systems and processes. Our advice focuses on your risks, objectives and decisions.

Here is how we can help.

Cyber risk & investments

Assess cyber risk in financial terms and compare the value of security investments.

Cyber impact assessments

An outage affects each business process differently. For each incident scenario, we analyse disruption, recovery work and financial losses, accounting for deadlines, catch-up capacity and dependencies.

  • Losses by scenario — with lost revenue, additional work and recovery costs assessed separately.
  • The effect of longer outages — showing when losses increase or a critical deadline is missed.
  • A comparison of contingency options — to identify which temporary way of working limits the consequences.

Financial cyber risk analyses

Using scenarios and probability models, we estimate how often cyber incidents could occur and the losses they could cause. Business data, threat information and specialist estimates inform the analysis.

  • Loss ranges and estimated probabilities — to weigh risks against what your organisation can absorb.
  • Visibility of large losses — including outcomes that an annual average can obscure.
  • The effect of uncertain assumptions — showing which additional information could change your decision.

Security investment analyses

A new tool, a larger team or improvements to existing controls: what does each option add? The analysis calculates costs and expected risk reduction, including overlap between controls and the risk that remains.

  • Comparable business cases — for the options you are actually considering.
  • The additional risk reduction — beyond your current controls, without counting the same contribution twice.
  • Decision thresholds — when would different costs or assumptions make another option more attractive?

Cyber resilience & assessment

Identify the attacks that matter and test whether your controls work.

Threat models and attack paths

Threat information becomes actionable when connected to your own environment. Accounts, permissions, systems and business processes are mapped into specific attack paths, including the conditions an attacker would need.

  • Attack paths to critical processes — including routes through suppliers or shared accounts.
  • Intervention points along each path — where access restrictions, detection or other controls could make a difference.
  • Specific validation questions — to check unconfirmed access paths and assumptions.

Cyber resilience scorecards

A scorecard brings scenario assessments and measurement results together into an overview of cyber resilience. Consistent criteria and a clearly defined scope explain what the score means and which changes can be compared.

  • Results for each attack scenario — with gaps and missing evidence shown separately.
  • Comparable follow-up measurements — separating improvement and deterioration from changes in assessment scope.
  • Evidence behind the score — so your team can identify the findings that need attention.

Control effectiveness measurement

For selected controls, we define which attacks they should prevent, detect or limit, then measure how they perform. Configurations, security data and test results provide the evidence for the assessment.

  • An assessment of each control — distinguishing demonstrated weaknesses from missing evidence.
  • Visibility of weak links — such as rapid detection followed by a response that comes too late.
  • Criteria for repeat measurements — so you can establish whether changes have had an effect.

Security validation

Targeted attack tests reveal what happens in practice. Avant Cyber conducts the tests or works with your team, using agreed scenarios, relevant variations and assessment criteria.

  • A test matrix with observations — showing what is blocked, detected and acted upon.
  • Differences between test variations — so one successful test is not treated as evidence for every attack path.
  • Specific retest criteria — to check whether a change resolves the identified weakness.

Business recovery

Understand your recovery time and what could prevent timely recovery.

Recovery and business disruption analyses

From incident to resumed operations, the analysis follows the full recovery sequence. Technical tests, process dependencies and the availability of staff and suppliers are combined into an evidence-based recovery path.

  • A business recovery timeline — showing the sequence of steps and what can realistically run in parallel.
  • The delays that determine recovery time — explaining why a successful restore does not yet mean operations have resumed.
  • Modelled improvement options — to identify which changes bring your recovery objective within reach.

Security finding prioritisation

Give your team an evidence-based order for what comes first.

Security finding prioritisation model

Findings are prioritised using attack opportunities, business impact and feasible actions. The model also connects individual tickets that together create a more serious problem and can be updated as new information becomes available.

  • An evidence-based ranking — explaining why one action should come before another.
  • Related findings grouped together — so your team can address an attack path rather than isolated tickets.
  • Visibility of temporary options — including the issues that remain after an intervention.

Security measurement & reporting

Have your security information assessed or improved, or new measurement and reporting systems built.

KPIs, KRIs and measurement frameworks

What should an indicator measure, which sources does it need and when is the result useful? Existing measurements are assessed against these questions, or a new measurement framework is designed and implemented, from definitions to calculations and source connections.

  • Unambiguous measurement definitions — making scope, numerator, denominator and measurement period explicit.
  • Connections across sources — revealing systems outside a tool report or exposure before a finding was discovered.
  • A repeatable measurement process — with calculations and checks your team can use and maintain.

Risk-driven dashboards

A risk-focused dashboard is designed around the questions you need to manage. Selected sources are connected and indicators developed, with data presented so you can track and explain changes.

  • A working dashboard — with the agreed measurements and access to the underlying data.
  • Separate technical and decision status — so a closed ticket or accepted risk is not mistaken for a resolved weakness.
  • Visible data quality — with missing or outdated data flagged alongside the relevant measurement.

Automated reporting

Individual exports and spreadsheets are replaced by an established reporting process. Source connections, data checks and calculations turn inputs into recurring reports, automated where your systems support it.

  • Less recurring collection work — through consistent processing of the connected sources.
  • Visible data delivery failures — a missing source does not silently appear as a reduction in security issues.
  • Traceable figures and maintenance arrangements — so your team can check and maintain the reports.

Board security reports

Board security reports are structured around the decisions at hand. Technical findings, costs and business consequences are translated into specific options, with supporting evidence suited to management and board discussions.

  • A clear decision to make — with options, consequences and required resources set out side by side.
  • Progress and remaining risk — so completed projects do not obscure attack opportunities that still exist.
  • Traceable supporting evidence — including the main assumptions, uncertainties and sources for follow-up questions.

Independent model reviews

An independent model review examines assumptions, data sources and calculations against the intended use. It also assesses dependencies and sensitivity to different inputs: a correctly calculated score can still lead to the wrong decision.

  • Findings and their consequences — showing which weaknesses materially affect the conclusion.
  • Visibility of critical assumptions — such as controls that can fail together because of a shared cause.
  • Targeted improvements and validation actions — to make the model better suited to the decisions it supports.

Address your security question with a clear plan.

One specific question is enough to start. We agree on what you need to decide or use.

  1. Discuss what you need.

    Tell us what is unresolved and what you need to decide or use. We agree on the deliverables, timing, costs and your team’s contribution.

  2. We do the work.

    We analyse, test or build what the project requires. You know in advance what information and coordination we need from your team.

  3. Use the result.

    You receive the agreed analysis, model or system. We explain how to use it and agree on who will maintain it if needed.

What to know before we start.

Is this useful alongside our security tools and dashboards?

Yes. We use what you already have and identify which questions remain unanswered. Where needed, we add information, test control performance or improve the measurement and reporting process. The project determines what is needed.

Can we start if our data is incomplete?

Yes. You do not need to organise everything first. We identify the information needed for your question. Existing data, specialist knowledge and focused tests can complement one another. We make remaining uncertainty clear.

How much time will this take from our team?

Your team shares available information, explains the environment and discusses the results. We carry out the agreed analysis and development work. We specify who needs to be involved and how much coordination is required. Testing responsibilities are agreed separately.

Can we use and maintain the result ourselves?

Yes. We agree in advance on how your team will use it. You receive guidance on use, calculations and limitations. Where maintenance is needed, we define what your team handles and what Avant Cyber may continue to provide.

Will we know the cost and what we receive upfront?

Yes. You receive a proposal covering deliverables, timing, costs and your team’s required contribution. You know what you are committing to. We discuss additional work before carrying it out.
