Alarming Facts On Cybersecurity

  1. According to the FBI, nearly $ 7 billion were lost in 2021 to cybercrime, which is growing yearly.
  2. More than half of all Americans have been victims of some form of cybercrime.
  3. The total cost of cybercrime to the US economy is estimated to be over $600 billion annually.
  4. Cybercrime is now the second most reported crime in the US, behind only drug trafficking.
  5. The average cost of a data breach globally is $4.35 million.
  6. 43% of all cyberattacks target small businesses.
  7. 60% of small businesses that are attacked are out of business within 6 months.
  8. 78% of organizations believe they are more vulnerable to cyber-attacks than they were last year.
  9. 1 in 4 businesses have experienced a ransomware attack in the past 12 months.
  10. The WannaCry ransomware attack in May 2017 affected more than 230,000 computers in 150 countries and caused billions of dollars in damage.

10 Reasons You Need Cybersecurity Services For Your Business in Walnut Creek

1. Data breaches are becoming more common

There’s no denying the fact that data breaches are becoming more and more common. In fact, a recent study found that 4145 data breaches occurred in 2021 – exposing more than 22 billion records. And, with how things are going, it will only get worse.

If your business stores any kind of sensitive data – whether it’s customer credit card information, employee social security numbers, or anything else – you need to be prepared for the possibility of a breach, and the best way to do that is to invest in cybersecurity.

2. The cost of a data breach is on the rise

According to the same study mentioned above, the average cost of a data breach is now $4 million. Considering the fact that 60% of small businesses go out of business within six months of a data breach, it’s clear that the cost of not investing in cybersecurity can be even higher.

3. Cybersecurity attacks are becoming more sophisticated

In the past, most cybersecurity attacks were carried out by amateurs who were simply trying to see if they could get away with it. But now, more and more attacks are being carried out by professional organizations with malicious intent.

What’s more, these attacks are becoming increasingly sophisticated. They’re using more advanced techniques and targeting specific businesses rather than just anyone who happens to be online.

4. Your business is at risk even if you’re not the target of an attack

Even if your business isn’t the specific target of a cybersecurity attack, you could still be affected. That’s because many attacks are carried out using what’s known as a botnet – a network of infected computers that can be used to launch an attack on any number of targets.

If your business is connected to the internet, there’s a risk that your computers could be part of a botnet without you even knowing it. And that could put you at risk of being involved in an attack, even if you’re not the intended target.

5. Cybersecurity threats are constantly changing

One of the biggest challenges facing businesses when it comes to cybersecurity is the fact that threats are constantly changing. What might have been a safe website to visit yesterday could be full of malware today. And, new threats are being created all the time.

That’s why keeping up with the latest cybersecurity news and trends is so important. By staying informed, you can help ensure that your business is as safe as possible from the latest threats.

6. Employees are a major security risk

Even if you have the best cybersecurity defenses in place, they can all be for nothing if your employees aren’t following best practices. After all, it only takes one person to click on a malicious email or download a harmful attachment for your whole business to be at risk.

That’s why it’s important to educate your employees about cybersecurity risks and ensure they know how to protect themselves and your business. Only then can you help ensure that your business is safe from its threats.

7. You could be held liable for a data breach

In some cases, businesses can be held liable for data breaches – even if they weren’t responsible for the breach itself. For example, if your customer credit card information is stolen in a data breach, you could be held liable for any fraudulent charges that are made.

Investing in cybersecurity is another reason why it’s so important. By doing so, you can help protect your business from the financial fallout of a data breach.

Who Needs Cybersecurity Services?

As our lives move increasingly online, so too do the risks we face from cybercrime. Businesses of all sizes are vulnerable to attack, and the costs of a successful breach can be devastating. That’s why cybersecurity is more important than ever before.

But what exactly are cybersecurity services, and who needs them?

What are cybersecurity services?

Cybersecurity services are designed to protect businesses and individuals from online threats such as viruses, malware, phishing scams, and data breaches. They can be provided by specialist companies, or as part of a wider IT support package.

There are many different types of cybersecurity service available, but some of the most common include:

  • Firewalls and intrusion detection/prevention systems
  • Encryption
  • Identity and access management
  • Vulnerability assessments and penetration testing
  • Security awareness training

Who needs cybersecurity services?

In short, anyone who uses the internet is at risk from cybercrime and could benefit from some form of cybersecurity protection.

However, businesses are particularly vulnerable to attack, and even a small company can face ruin if it suffers a successful data breach. That’s why many businesses now invest in comprehensive cybersecurity packages that cover all aspects of their online operations.

Backup and Disaster Recovery Services

What is backup and disaster recovery service?

Backup and disaster recovery service provides a comprehensive solution for organizations to protect their data and ensure continuous business operations in the event of a disaster. The service helps organizations recover lost or corrupted data, restore applications and systems, and resume business operations quickly and efficiently.

What Are The 3 Types Of Backups?

  1. Full backups
  2. Incremental backups
  3. Differential backups

A full backup is a complete copy of all the data on a given system. This type of backup captures everything, so it can be used to restore a system to its original state.

An incremental backup only copies files that have changed since the last backup. This type of backup is typically used in conjunction with a full backup, so that only the most recent changes need to be restored in the event of data loss.

A differential backup copies all files that have changed since the last full backup. This type of backup is typically used in conjunction with a full backup, so that only the most recent changes need to be restored in the event of data loss.

Platform as a Service (PaaS): PaaS providers offer businesses a platform for developing, running, and managing applications in the cloud. PaaS platforms often include everything businesses need to build and run an application, including operating systems, development tools, middleware, and storage.
