Welcome to Shadow Tier
Shadow Tier brings together cyber security signals that matter for the digital supply chains companies rely on.
Welcome to Shadow Tier: a place where cyber intelligence becomes more practical, timely, and useful for organizations that need a clearer view of their digital supply chain.
Companies are increasingly connected to vendors, software platforms, cloud environments, data processors, and external service providers. An incident at a supplier can therefore become just as relevant as an incident inside your own organization. Shadow Tier was created to make that outside world easier to see and understand.
What is Shadow Tier?
Shadow Tier collects and organizes signals about cyber incidents, vulnerabilities, and threat developments that may affect the supply chains of companies. These signals can include data breaches, ransomware events, disruptions at digital service providers, exposed systems, sector trends, and other developments that may point to supplier risk.
The goal is not to add more noise to the daily flow of security news. The goal is to make relevant signals easier to recognize: what happened, who may be affected, which supply chain relationship might matter, and why the signal deserves attention.
Why this website exists
Many organizations understand that supply chain risk matters, but they often lack an accessible and up-to-date view of what is happening beyond their own perimeter. Traditional monitoring tends to focus on internal systems, tickets, and controls. Shadow Tier adds a view of the ecosystem around the organization.
That helps security, compliance, and risk teams answer questions such as:
Which incidents are relevant to our suppliers or sector?
Which companies, domains, or services appear in current cyber signals?
Which developments should be followed up with procurement, legal, IT, or management?
Where could supply chain impact emerge before it becomes visible internally?
From signal to action
A signal is not a conclusion. It is an indication that needs context. Shadow Tier helps surface that first indication and connect it to relevant business information. From there, teams can decide whether follow-up is needed: checking a supplier, reviewing a contractual risk, discussing a vulnerability, or simply continuing to monitor the development.
The website will keep evolving with new articles, wrap-ups, and signal overviews. Each publication is meant to reduce the distance between cyber intelligence and practical decision-making.
Who Shadow Tier is for
Shadow Tier is for organizations that want to look beyond their own perimeter. It is for teams working on NIS2, supplier management, third-party risk, security awareness, incident response, or digital resilience. It is also for anyone who wants to understand how cyber events in the market can affect day-to-day business operations.
Welcome. From here, we are building a sharper view of the digital supply chain.
