How Long Does It Take to Detect a Cyberattack?

The average time it takes to detect cyberattacks or security breaches varies depending on a number of factors. Still, based on recently gathered data, a few trends emerge — and they might surprise you.

Typical Cybersecurity Attack and Containment Time

A look at some of the recent cybersecurity data shows a broad range from days to months to detect and contain a breach or attack. It also depends on whether the hacker discloses the breach or if the victim organization discovers the breach, themselves.

Verizon’s 2025 Data Breach Investigations Report (DBIR) analyzed over 22,000 breaches across 139 countries. This report showed that the median length of time to discover a data breach is changing. In recent years there was a larger gap between breaches detected in ‘days or less’ vs. ‘weeks or more’. Researchers have found that this gap has narrowed because of more hackers demanding a ransom, therefore disclosing the breach. For non-hacker-disclosed breaches the median length of time was found to be 24 days – that’s six days shorter than the median determined just two years earlier.

The IBM Cost of a Data Breach Report 2024, which examined 604 organizations in 16 countries, identified that breaches involving stolen or compromised credentials took the longest to identify and contain (292 days) of any attack vector. This report also found that similar attacks involving employees and employee access also took a long time to resolve. Phishing attacks were found to last an average of 261 days, while social engineering attacks took an average of 257 days.

Cybersecurity Risk Factors

Cyberattacks target organizations of all sizes. Often, small to medium-sized businesses (SMBs) mistakenly feel that hackers will only target large organizations. But studies have shown that a cyberattack forces nearly one in five SMBs to shut down.

How you proactively prepare could determine how much of a chance a hacker has to break through your defenses. Preparing now could save your business from big headaches and could limit the potential for damage.

Two major cybersecurity risk factors to consider are:

• Where are you vulnerable to cyberthreats?
• If a hacker is able to capitalize on a vulnerability, what's the risk to your business? 

During a cyberattack, you could have your files encrypted and backups deleted. If this ransomware attack happens, the hacker may ask you to pay a ransom to unlock your data.

If your data is locked for an extended length of time, you could even be putting your organization at risk of going out of business.

What to Do During a Cyberattack

Once a hacker has entered through a compromised device and onto your network, their main goal will be to move slowly and undetected through your system while watching your internal data.

This phase of undetected watching and waiting is called dwell time. If not detected by the business right away, it’s possible a hacker could dwell within your network for months, gathering information before revealing themselves. During this time they could be searching for information such as:

• Bank account details (to access your finances)
• Supplier invoice patterns (to learn how to mimic your suppliers and send imposter emails)
• The configuration of your backups (to understand how to encrypt them)

This is why it’s crucial to be prepared. We recommend that every organization has a cybersecurity incident response plan in place. Use this plan to document such information as:

• Root cause
• Entrance point
• What data was accessed or taken
• Extent of exposure during the attack
• How you’ll remove the hacker from your system
• How you’ll restore your files
• Communication protocols for internal and external audiences
• An incident recap to document lessons learned and new prevention measures

Already having such a plan in place ahead of time can go a long way and is one of many proactive measures to take.

Prepare Your Defenses Against Cybercriminals

You can be proactive or reactive. Reactive responses generally mean a hacker has executed their attack and released their payload into your environment. This is also referred to as a zero-day attack. Having to react to a hacker could be devastating and costly to your business.

A better way to detect a cyberattack is proactively by installing tools to spot malware and other intrusions and protect your business.

The first important tool is an Endpoint Detection and Response (EDR) solution, which looks for odd occurrences and behaviors involving your data. You’ll also want to implement a Managed Detection and Response (MDR) solution to provide 24/7 monitoring of your networks, endpoints and cloud environments. MDR monitors logged data across your networked infrastructure — searching for any indication of a threat presence.

Both MDR and EDR search for malicious actors on your network. They proactively watch your network and alert you and your security partner to ensure that the malicious actors are discovered and kept out of or removed from your system before they inflict more damage.
