A Cyberattack as a Race Against Time: Why Defense Speed Decides
It’s Monday morning. Your team discovers a critical vulnerability—or your vendor flags one. You plan to patch it by Friday. But by Wednesday, attackers have already breached your network, and chaos erupts.
This isn’t a hypothetical situation—it’s a real and growing risk. Fortinet’s latest report shows attackers are now exploiting critical vulnerabilities within just 24 to 48 hours.
As AI speeds up every process, the consequences of each action arrive faster and hit harder. A single move today can set off a chain reaction that spreads further and faster than ever before.
In this post, we break down the key findings from Fortinet's latest report and explain why slow defense has become a critical business risk.
24–48 Hours: The New Standard for Cyber Defense
According to Fortinet’s 2026 Global Threat Landscape Report, time to exploit (TTE)—the period between a vulnerability’s disclosure and active exploitation—continues to shrink as automation accelerates attacks.
In 2025, TTE consistently sat at just 24 to 48 hours. Exposed digital identities remained the main driver of industrialized intrusions. Fortinet’s FortiRecon threat intelligence service reported that 4.62 billion infostealer malware logs were traded or shared on the dark web, and the market for stolen credentials grew by nearly 79% compared with 2024.
The report paints a picture of a cybercrime ecosystem that increasingly resembles a mature industry, with ransomware operations continuing to evolve. Nearly half of the suspicious activity Fortinet observed involved the abuse of legitimate tools rather than custom malware. Meanwhile, attackers are exploiting newly discovered vulnerabilities faster than ever.
Defense Speed: Why Locking the Door Is No Longer Enough
For years, cybersecurity acted like a lock—the stronger it was, the safer you felt. Companies poured money into stronger firewalls, confident attackers would stay out. That assumption no longer holds.
Attackers often don't need to break down the door. They often already have the key: available through stolen credentials or access being traded in underground markets. The real question isn’t whether someone can break in—it’s how fast you’ll detect the intrusion and how quickly you can stop it.
Defense speed is an organization's ability to detect a threat in time, assess it, and neutralize it before the attacker achieves their goal. For most companies, building cyber resilience doesn't mean replacing their entire infrastructure. It means seeing more clearly what's happening across their own systems and responding faster when something looks wrong.
See Your Network Through an Attacker’s Eyes
A cyberattack doesn't start the moment an attacker gets in. It starts much earlier, while they quietly map what you expose to the internet, buy stolen passwords on underground markets and lay the groundwork.
The breach itself is just one link in a longer chain. Afterward, the attacker can stay in your environment, exfiltrate data, demand a ransom, and damage your business. That's why it's a mistake to view threats through isolated statistics or trends. To protect yourself, you need to understand the attacker's entire path, from the first step to the last.
Kash Valji, vice president of Fabric CSE for EMEA and APAC at Fortinet, stresses the importance of active reconnaissance and regularly checking how your organization looks from the outside. This approach helps teams separate real threats from the growing noise of automated scanning and focus resources where they're actually needed.
Most organizations still assume an attack begins with someone scanning their network. In reality, their credentials may have been sitting on a forum for months. FortiRecon intelligence shows that a significant share of today's cyber exposure is collected, structured and commercialized in advance through dark web ecosystems.
How FortiRecon Reveals What Attackers Already Know
Fortinet positions FortiRecon as a threat exposure management solution. It lets organizations manage exposure and assess vulnerabilities systematically, instead of reacting only after an incident. A key part of this approach is visibility into what attackers already hold.
FortiRecon monitors underground forums and dark web marketplaces. It detects when access brokers start selling your organization's credentials, data, or network access. Your security team gets clear context immediately, so they can respond before attackers act.
Security Tools for the AI Era
The good news is that responding to AI-driven threats doesn't necessarily mean adding more standalone security tools. Many current solutions can be upgraded with new capabilities, so your defenses can keep pace with automated adversaries. By consolidating visibility and enabling automated detection and response across the attack lifecycle, organizations can reduce complexity and move from fragmented alerts to coordinated action.
Attackers have accelerated their operations. The challenge for defenders is to eliminate the gaps and delays that give them that advantage.
