Impact in cybersecurity refers to the effect or consequence that a security breach or cyber-attack can have on an organization, individual, or system. This could mean loss of confidentiality, integrity or availability of data, disruption of services, financial losses, or damage to an organization’s reputation. It can also extend to broader societal outcomes, like disruptions in critical infrastructure or the economy.

Impact Examples

1. Small Online Retail Business

The business has diligently built its online presence and accumulated a considerable customer base. One day, it fell victim to a cyber attack that targeted their customer database, specifically credit card information.

This breach stripped away the financial security of the company’s trusting clientele. Their confidential credit card information was exposed, which led to unauthorized and fraudulent transactions. The clients found charges on their cards they didn’t authorize, hinting at stolen funds.

The aftermath did not only involve financial loss. The trust that took years to build rapidly diminished. Their customers, fearing another breach, became hesitant to continue business transactions. Aside from customer trust, the potential legal consequences following such breaches could further strain the company’s financial resources.

2. Healthcare System Network

A healthcare system heavily relies on its network for efficient operation. One day, this system was infected by a vicious ransomware. This type of malicious software typically encrypts files and demands a ransom for their release. Essential patient data was suddenly trapped behind an encryption wall.

With patient records being inaccessible, the hospital’s services were severely disrupted. Critical care, consultations, and even routine check-ups were potentially affected. The inability to access these digital records put the wellbeing of patients at risk along with causing a delay in their treatment plans.

The consequences further stretched into the loss of public trust and potential financial burden. The hospital had to bear reputational damage, as people questioned the system’s security measures. Besides, the financial loss both from the disruption of services and the potential payment of the ransom further expanded the impact of the breach.

3. Individual User

An individual received an authentic-looking email and clicked the embedded link without suspicion. This was a trap, a phishing attempt, successful at that. Unknowingly, the individual installed malware on their computer through this click.

Following this, the person’s personal details stored on the computer were compromised. Personal information like bank details, social security numbers or private correspondence could now potentially be in the hands of malicious entities. This could lead to a range of impacts such as identity theft, fraudulent activity or even blackmail.

The computer system itself was affected as well. After the malware installation, the user may notice their device’s performance suffering. It may no longer function optimally due to potential interference or data manipulation by the malware. This not only causes inconvenience but could also lead to further loss of sensitive information, amplifying the impact for the individual user.


The impact of cybersecurity breaches extends beyond immediate technical disruption. It ripples into financial loss, reputational damage, and personal harm, underlining the essential role of robust cybersecurity measures in maintaining trust and operation across various sectors.
