#### Cybersecurity is in the news a lot, and typically in a bad way.

We learn about **Cybersecurity** through well-publicized **cyberattacks** on major financial institutions, corporations, social media platforms, hospitals and cities. These attacks cost organizations and individuals billions of dollars a year, and hackers show no signs of slowing down. **If anything, attacks are growing more clever and complex by the day. They can involve:**

- Identity theft or theft of other sensitive data;
- Ransomware, where a hacker locks up a computer system and offers to reopen it for a price;
- Virus or Trojan Horse attacks that disable individual computers or export data from them;
- Denial-of-service attacks that disable computer servers; and
- Keylogging attacks that steal passwords or financial information.

The industry has developed myriad [Cybersecurity](https://stellarcyber.ai/company/riskshield-cyber-insurance-program-for-mssps/)
 tools to combat these threats. In the beginning, there were firewalls placed between private networks and the Internet to protect corporate servers, along with anti-virus software that detected and guarded against attacks on individual computers. These have evolved over time so that now there are dozens of **Cybersecurity** systems that aim to protect specific parts of the **cyberattack** surface, from network endpoints and individual computers to servers, applications and websites.

**Specific solutions include:**

- Endpoint **[Detection and Response](https://stellarcyber.ai/platform/capabilities-ndr/)** systems (EDRs)
- Security Information and Event Managers (SIEMs)
- User Event Behavior and Analysis (UEBA)
- Intrusion Detection and Protection Systems (IDPS)
- Next-generation Firewalls
- Anti-Virus Software
- Identity Management Systems
- Data Loss Prevention Systems

The **Cybersecurity** market has seen an explosion of solutions for specific problems, so much so that a typical enterprise has a dozen or more **Cybersecurity** systems in place. Each system requires one or more security analysts to manage and monitor it, so security staffs have grown over time. And despite ramped-up efforts to train new security analysts, these professionals are relatively scarce and command high salaries.

But even with a dozen **Cybersecurity** systems in place, it can be difficult to spot complex attacks. After all, each analyst sees only a small part of the whole picture, and complex attacks can involve performing relatively innocent-looking operations in several different parts of the infrastructure. For example, an executive logs into the network at 2AM. Then, the executive establishes a connection to a server in Russia. Finally, the executive begins exporting data from the corporate server to the server in Russia. These events would be caught by different **Cybersecurity** systems, and it would be up to the separate analysts to compare notes and determine that an attack was underway – a process that could take hours, days or even weeks.

Today, the state of the art in **Cybersecurity** is to collect data from all of the disparate security tools, correlate it to reveal complex attacks, and respond immediately when an attack occurs. So far, only Stellar Cyber has such a comprehensive approach. Stellar Cyber’s platform can collect data from existing firewall, **[SIEM](https://stellarcyber.ai/platform/capabilities-ng-siem/)**, EDR, IDPS and other systems as well as its own sensors to capture a complete picture of the **Cybersecurity** situation, and then correlate that data to discover [cyberattacks](https://stellarcyber.ai/cybersecurity-challenges-and-solutions/)
. This approach is not only faster and more accurate at detecting attacks, but it also increases analyst productivity and reduces operational costs.

Hackers will of course keep inventing new **Cybersecurity** exploits, but by collecting and analyzing data from throughout the cyber kill chain, analysts will be much better prepared to discover them. Stellar Cyber offers that power today.
