An information technology risk assessment is a tool for mitigating risk within an organization’s digital ecosystem. By identifying risk within an organization’s IT environment and its third-party network, a risk assessment can help to evaluate risk severity and determine which areas of risk should receive priority for remediation.
Residual Risk
What is Residual Risk?
Residual risk refers to the level of risk that remains after all possible measures have been taken to mitigate or eliminate a particular risk. It is the risk that an event will still occur despite the implementation of risk management controls or strategies.
Organizations face residual risk in various aspects of their operations, including cybersecurity, financial investments, project management, and supply chain management. The concept of residual risk acknowledges that it is impossible to completely eliminate all risks and that some level of risk will always remain even after implementing risk management measures.
The primary goal of risk management is to reduce residual risk to an acceptable or tolerable level, taking into account the cost-benefit analysis of further risk mitigation efforts and the organization's risk appetite.
Residual Risk in Cybersecurity
Residual risk in cybersecurity refers to the level of risk that persists even after implementing various security measures and controls. Despite organizations' best efforts to mitigate cyber threats, residual risk remains inherent due to the evolving nature of cyber threats and the complex technological landscape because of many factors:
- Dynamic Threat Landscape: Cyber threats are constantly evolving, with new attack vectors, malware variants, and vulnerabilities emerging regularly. Even with robust security measures in place, organizations may still be susceptible to unknown or zero-day vulnerabilities, leading to residual risk.
- Human Factors: Human error, negligence, or malicious insider activities can contribute significantly to residual risk in cybersecurity. Despite extensive training and awareness programs, employees may inadvertently fall victim to social engineering attacks or inadvertently expose sensitive data, leading to potential breaches.
- Third-Party Risks: Organizations often rely on third-party vendors, suppliers, or service providers for various aspects of their operations. However, these third parties may introduce additional cybersecurity risks, such as supply chain attacks or data breaches, contributing to residual risk for the organization.
- Legacy Systems and Infrastructure: Legacy systems or outdated infrastructure may contain unpatched vulnerabilities or lack sufficient security controls, increasing the residual risk of exploitation by threat actors.
Calculating Residual Risk
Residual risk is a critical concept in risk management, reflecting the level of risk that remains after all mitigation strategies have been applied. It can be calculated using the formula:
Residual Risk = Initial Risk - Mitigated Risk
Initial Risk:
This is the initial level of risk before any risk management controls or strategies are implemented. It represents the potential impact and likelihood of an event occurring in the absence of any risk mitigation measures.
Mitigated Risk:
This is the level of risk that remains after implementing risk management controls or strategies. It reflects the effectiveness of the risk mitigation measures in reducing the impact or likelihood of an event occurring.
Managing Residual Risk
Effectively managing residual risk is crucial for organizations to maintain a robust security posture. This involves implementing various strategies to address the remaining risk after primary mitigation efforts.
Risk Acceptance
In some cases, organizations may choose to accept residual risk if it falls within their risk appetite and the cost of further mitigation is deemed too high.
Risk Transfer
Organizations can transfer residual risk to a third party through insurance policies or outsourcing arrangements.
Risk Avoidance
In certain situations, organizations may choose to avoid activities or decisions that carry a high level of residual risk.
Risk Mitigation
Organizations can implement additional risk management controls or strategies to further reduce residual risk.

Information Technology Risk Assessment
Choosing A Superior Information Technology Risk Assessment
As the size of your third-party network grows, the risk posed by your relationships with vendors increases as well. According to a recent report by Bomgar 1, more than 180 vendors have access to a company’s network in a single week – more than double the number from 2016. Monitoring and mitigating vendor risk requires a superior information technology risk assessment solution. Traditional methods like a risk assessment questionnaire or cyber security risk assessment checklist provide some value, but they can’t deliver the continuous monitoring capabilities required to manage risk year-round.
Bitsight can help. Using Bitsight’s industry-leading Security Ratings, Bitsight for Third-Party Risk Management provides automated tools for continuously measuring and monitoring the security posture of your vendor network.

What Bitsight’s Information Technology Risk Assessment Can Tell You
With Bitsight Third-Party Risk Management and Bitsight Security Ratings, you can answer the three critical questions that should be part of every third-party risk management program.
Which vendors should you focus on during assessments or audits?
Bitsight Security Ratings deliver all the insight and actionable data you need to decide which vendors to prioritize for information technology risk assessments. Bitsight Security Ratings provide an easy-to-understand numerical rating that correlates to each vendor’s security posture. You can also grade vendors by criticality of the relationship, the type of information exchanged with the company, past interactions, and 12 months of historical security performance. By focusing your information technology risk assessments on more critical vendors, you can better prioritize your resources and staff time on remediation where it will make the most impact to your business, instead of spending valuable time on areas of insignificant risk.
What questions should you focus on in your assessments?
Security risk assessments shouldn’t be a one-size-fits-all exercise. Tailoring your assessment to the specifics of each vendor will give you greater clarity into the risks each company poses. Bitsight Security Ratings make it easy to customize the questions in your assessment based on a vendor’s individual rating and security history. For example, you may ask questions about security controls that seem to be missing or historically ineffective security policies. You can also use Bitsight to validate many of the answers provided by vendors on their risk assessment.
How often should you engage with vendors?
Bitsight Security Ratings can help to determine the best cadence for your information technology risk assessments. Rather than sticking to a standard annual assessment, you can allow your engagement with vendors to be more event-driven. A change in a vendor’s Security Rating, for example, can serve as the driver to check in with them. Vendors with consistently higher security ratings may need less frequent contact than vendors whose ratings are trending lower.
How Bitsight Security Ratings work
Bitsight Security Ratings are generated from objective, verifiable information about a company’s security performance. Ranging from 250 to 900, Bitsight’s daily ratings provide a data-driven, dynamic, quantitative measurement of the security posture of an organization or its third-party vendors. In addition to quantifying overall cybersecurity performance, Bitsight ratings can deliver grades on individual risk vectors as well.
Bitsight Security Ratings are updated daily, so they represent a near real-time continuous monitoring solution. Ratings also provide a common language that can be shared by technical and non-technical individuals, facilitating data-driven decisions between cybersecurity professionals and executive or board-level individuals.
Bitsight Security Ratings are calculated using a proprietary algorithm that analyzes externally observable data in four areas of cybersecurity: compromised systems, security diligence, user behavior, and data breaches. This outside-an approach to rating security performance requires no information from the rated entity.
Bitsight Security Ratings are independently verified to correlate with the risk of a data breach. For example, companies with a Bitsight rating of 500 or lower are nearly 5 times more likely to experience a breach than those with a rating of 700 or more.
