How much does it cost and how long does it take for a medium-sized company to recover from a cyberattack?

A cyberattack can go from being a technical problem to a business disruption in a matter of minutes. A systems outage can affect billing, production, logistics, customer service, and access to information, while the company continues to incur its usual operating costs.

In Spain, the average cost of a security breach reaches $3.9 million, while a business interruption can cost between €4,000 and €7,500 per minute. And the cost of technical recovery is only part of the impact: up to 43% of organizations can take between one and three months to fully recover after an incident.

That is why calculating the cost of a cyberattack is not simply a matter of adding up the technical team's bill. You also need to consider how much it costs to stop operations, how long it takes the company to resume normal activity, and what consequences the exposure of information may create.

How much does a cyberattack really cost a mid-sized company?

The cost of a cyberattack depends on the systems affected and the time required to restore operations. A company may have to cover immediate technical expenses while also dealing with losses caused by business interruption.

In mid-sized companies, an incident can also affect several departments simultaneously. The longer critical systems remain unavailable, the greater the cumulative impact.

How long does it take a company to recover from a cyberattack?

Containing an attack and fully restoring operations are two different processes. A technical team may be able to isolate a threat quickly, but returning all systems to normal operation can take weeks.

Recovery time depends on factors such as the scope of the incident, the availability of backups, infrastructure segmentation, and the ability to identify which systems have been compromised.

That is why being able to detect an attack quickly is not enough. The company also needs to know how long it would take to restore and recover its critical services and which processes should be prioritized to maintain business continuity.

What factors determine recovery time?

Not all cyberattacks have the same consequences. Several factors can significantly speed up or slow down recovery:

• Incident scope: the more devices, servers, or applications affected, the greater the recovery effort.
• Backups: having protected backups and verifying them regularly makes it easier to restore systems.
• Infrastructure visibility: understanding what happened and how far the attacker reached allows decisions to be made more quickly.
• System segmentation: separating critical services limits the spread of an attack and allows specific areas to be recovered without waiting for the entire infrastructure.
• Response plan: having defined procedures prevents improvisation during the first hours of an incident.

Preparation can make a significant difference between restoring essential services quickly and keeping part of the company offline for weeks.

What should you do during the first hours of a cyberattack?

When an intrusion is detected, acting quickly is critical, but doing so without a defined procedure can make the investigation more difficult or even increase the impact.

The initial response should focus on:

1. Contain the threat: isolate affected devices or systems to prevent the attacker from continuing to move through the infrastructure.
2. Determine the scope: identify which systems, accounts, and data may have been compromised.
3. Protect identities: review affected credentials, terminate active sessions, and strengthen access controls.
4. Preserve evidence: retain logs and affected systems to investigate the origin and progression of the incident.
5. Coordinate the response: involve IT, cybersecurity, management, and, when appropriate, legal and compliance teams.

The initial goal is not to restore everything immediately, but to regain control of the infrastructure and establish a secure recovery strategy.

Can a company recover quickly from a cyberattack?

Yes, but recovery speed largely depends on what was prepared before the incident.

A company with verified backups, continuous monitoring, response procedures, and properly segmented infrastructure is in a very different position from one that has to improvise every decision during an attack.

Recovery must also verify that systems are truly clean before returning them to production. Restoring operations too quickly without eliminating the root cause of the compromise can lead to additional incidents.

How can you reduce the cost of a cyberattack?

The best way to reduce the cost of an incident is to act before it happens. This is not simply about adding more tools, but about ensuring that different security measures work together.

Monitoring and early detection

Continuous monitoring helps identify anomalous access, lateral movement, and suspicious behavior as it happens. The sooner an intrusion is detected, the greater the chance of containing it before it affects critical systems.

Access control and MFA

Applying the principle of least privilege and multifactor authentication reduces the chances that a compromised account can be used to access critical organizational resources.

Backups and recovery

Backups must be protected against attacks and tested regularly. Having a backup is not enough: you need to know that it can actually be restored and how long the process will take.

Security audits and testing

Cybersecurity audits and penetration testing help identify vulnerabilities and insecure configurations before they can become an entry point for attackers.

Employee training

The human factor continues to play an important role in many incidents. Training employees and conducting simulations can reduce the risk associated with phishing, social engineering, and other techniques used to obtain access.

How can a mid-sized company prepare to recover from a cyberattack?

Preparation is not just about preventing an intrusion. An effective strategy must also address how to detect, contain, and recover operations when a threat manages to get past the initial defenses.

This requires knowing which assets are critical, controlling access, maintaining continuous monitoring, reviewing vulnerabilities, and regularly verifying that recovery mechanisms work as expected.

The goal is to reduce two variables that determine much of an incident's economic impact: the scope of the attack and the length of the disruption.

Proactive cybersecurity to reduce the impact of an attack

The cost of a cyberattack does not end when the threat is removed. Technical recovery, business interruption, incident investigation, and potential consequences involving data can extend the impact for weeks or months.

That is why ESED works with a managed cybersecurity model based on prevention, continuous monitoring, and response, helping companies detect threats, reduce their exposure, and maintain their ability to respond to incidents.
