Is One Source of Cyber Threat Data Enough to Protect Your Business? The short answer is no

For years, threat data feeds have been viewed by some as a fairly basic component of cybersecurity, functioning primarily as real-time digital "wanted lists." I believe that view overlooks their true value. Data feeds form the very foundation of a company's overall digital defenses and, consequently, its business resilience. Think of data feeds as fuel for a vehicle: poor quality fuel limits performance, no matter how advanced the car is. To ensure reliability, they must be accurate, timely, and above all, comprehensive. This is exactly why utilizing data from multiple feed providers is a game-changer.

Let’s take a look at the broader cybersecurity landscape. Businesses continue to suffer losses from breaches despite significant investments in cybersecurity. In fact, 72% of industry specialists have observed an increase in the number of cyberattacks, while global spending on cybersecurity solutions and services is projected to reach $302 billion by 2029 (according to Forrester). Meanwhile, the pace of cyber threats is accelerating. AI is making attackers more capable and enabling them to operate faster and at greater scale, while the volume of fragmented data is growing. At the same time, two out of every three organizations report moderate-to-critical gaps in their internal cybersecurity expertise.

These figures illustrate a paradox: spending is increasing, yet defensive efficiency remains flat and the pressure on security teams does not ease. The root cause may lie in the foundation: without high‑quality, timely threat data, even the most advanced SIEM, SOAR, EDR, XDR, or NGFW cannot deliver their full potential. Meanwhile, decisions based on incomplete or insufficient data can force security teams to spend substantial time and resources investigating non-existent threats or following the wrong track. The potential consequences are known - from direct financial impact, with the average data breach costs about $4.4 million to data leaks, and operational disruption.

The priority, therefore, is to minimize mean time to detect and respond. Threat intelligence, and specifically the data feeds powering it, strengthens existing security controls. It provides the context needed to prioritize alerts, investigate threats, and drive faster, more accurate decision-making. Ultimately, an investment in data feeds enrichment should be treated as a direct investment in business resilience.

Where threat data feeds come from

Data feeds are curated streams of cyber threat intelligence that deliver a broad range of vetted indicators in a machine-readable format. Security tools, like SIEM and XDR, automatically compare incoming traffic or logs against this information and generate alerts when a match occurs.

Our feeds are built by continuously aggregating raw threat indicators from a wide range of sources. One of the key sources is Kaspersky Security Network, which provides anonymized telemetry from protected endpoints across over 200 countries and territories. Kaspersky Expertise Centers[1] also provide crucial input, analyzing malware, APT campaigns, financial and industrial threats, vulnerabilities, incidents, and new attacker techniques. Additionally, we employ honeypots, spam traps, web crawlers, passive DNS, botnet monitoring, partner data, open‑source information, and other channels.

Another crucial step includes analysis, validation and enrichment of the collected data. At Kaspersky, indicators are first correlated with actual detections across protected systems to evaluate how a threat behaves in a real infrastructure. Then, automated filtering compares data against both massive whitelists of trusted files, domains, and IP addresses and a curated list of known malwares. This effectively filters out safe entities from entering malicious feeds. To handle complex or ambiguous indicators we involve machine learning models and human-expert analysis.

To keep feeds relevant, constant re-validation is another essential component. Any Threat Intelligence has limited validity: an IP address that was malicious yesterday might be clean today, and a hash of a malware sample can become obsolete as the as that specific malware falls out of use.  To stay actionable, our data feeds are refreshed regularly, with certain feeds updated every twenty minutes.

No matter how proud we are of our own feeds, or how many awards they have received, organizations achieve better security by sourcing data from multiple providers.

Here is why:

Geographical & infrastructure blind spots

Local vendors tend to have more detailed insights into regional threats but lack global visibility. Global providers without a broad presence in diverse markets may see attacks that have not yet reached a specific region, but without a presence in that specific market, they won't warn about region-specific threats. A clearer picture can be achieved by integrating these approaches or utilizing feeds from a global vendor with coverage in the country where the company operates.

Limited context

Different feeds provide different details about the same threat. One provider might simply deliver a malicious file hash (an IoC). Another will send the same hash but enrich it with crucial context: 'This file attributes to the Lazarus group, targets a Microsoft software vulnerability, and is used for cyberespionage.' This allows the SOC team to triage and prioritize the incident instantly.

Telemetry limitations

Cyber threats are rarely global from day one. If a new campaign strikes an organization protected by a specific vendor, that vendor’s threat intelligence feeds will reflect the danger before others notice it. Yes, feeds from a single provider offer fast reaction for the threats known by this provider, but they only see a fraction of the landscape. That is the reason why many organizations use from 2 to 5 different feeds providers in their infrastructure.

Duplication and noise

Each security vendor relies on proprietary algorithms, machine learning models, and data validation workflows. If a single provider suffers a technical glitch or introduces a false positive, trusting that vendor blindly could force your SIEM or XDR platform to block legitimate traffic or waste time on false alerts. That is why it is critical to evaluate the reliability of feed providers, review this parameter on a regular basis, and incorporate it into the triage process.

Leveraging multiple threat intelligence sources is not redundancy for the sake of redundancy. It is a way to minimize blind spots. In cybersecurity, a 'second opinion' often carries immense practical value. However, it is not enough to simply combine multiple threat intelligence providers – it is important to choose appropriate ones, considering the following aspects:

·        Source of information: compare several data feeds to identify whether data originates from the vendor’s own data, open‑source feeds, or a combination of both. Pro tip: the most valuable threat intelligence feeds are generated by the most heavily targeted regions, because the volume of attacks there produces a richer set of indicators.

·        Reliability: Reliable threat intelligence is accurate and low‑noise. Confirm it by checking the source’s reputation, comparing with other feeds, and ensuring its low false‑positive rate.

·        Freshness: provider should continuously update their data feeds, as the maliciousness of data can evolve over time and make outdated information a potential security risk.

·        Type of data: basic indicators, such as URLs, IP addresses, hashes, and additional information the vendor provides besides them should be relevant to specific needs of the organization.

·        Licensing model: it should be evaluated to ensure it fits the requirements of the organization and offers the appropriate level of access, scalability, and compliance.AskExplain

·        Expert support: A vendor's able to provide expert support will be able to help you in case additional information will be needed about threat.

To sum up, while some CISO skimp on threat data feeds, they in fact require a very precise approach. When talking about the foundations of your businesses cybersecurity, scrupulousness is rewarding. If you are looking for data that will ease burden on your team and bring ROI, I recommend not relying solely on vendors’ promises. Validate feeds through pilot projects, test feeds against your own environment, assess how these tools work together, and measure their practical impact on cybersecurity outcomes.
