Zero Trust Security Strategy: Reduces Cyber Attack Damage by up to 50%

Zero Trust Security market is forecast to reach $92 billion by 2030. Find out how this model helps businesses reduce risk costs by 50% and solutions from IPSIP Vietnam.

According to IBM's "Cost of a Data Breach" report, organizations deploying a Zero Trust Security strategy saved an average of $1.76 million (equivalent to a nearly 50% reduction in costs) when handling data breaches compared to those that have not deployed it.

This chart compares the cost of troubleshooting between businesses with and without Zero Trust.

In 2024, a wave of Ransomware attacks in Vietnam caused many systems to be "paralyzed," causing damage amounting to hundreds of billions of VND. In that context, Zero Trust security is no longer a distant technical concept, but has become a "vital shield" to protect digital assets.

1. What is Zero Trust Security? The End of the "Firewall" Era

Zero Trust Security is not a single software product. It is a cybersecurity strategic framework based on the principle: "Never Trust, Always Verify".

Unlike the old mindset, Zero Trust security eliminates the concept of a "safe zone" inside the internal network. All access, whether from the CEO or IT staff, whether sitting at the office or a coffee shop, must be strictly checked before touching data.

To visualize the superiority of Zero Trust security, look at the following example:

• Traditional Security: Just pass the main gate (Firewall), and users can move freely. If a Hacker seizes an employee account, they can silently steal all data.

• Zero Trust Security: Even if entered the lobby (logged in), users still need a key card to take the elevator, and that card only opens the specific allowed room door. This mechanism isolates risks and prevents malware from spreading.

2. Why is the Zero Trust Security Market Forecast to Reach $92 Billion by 2030?

The world is witnessing a huge shift of money into this technology. According to data from Northwick Cyber and Grand View Research, the global Zero Trust Security market size is expected to hit the $92 billion mark by 2030, with a Compound Annual Growth Rate (CAGR) of up to 16.6%.

Drivers fueling this boom include:

• The disappearance of the physical perimeter: Data moving to the Cloud and mobile devices makes traditional firewalls ineffective.

• Remote Work: The need to access systems from everywhere requires a stronger authentication mechanism than old VPNs.

• Insider Threats: Zero Trust Security is the only solution to effectively control risks from employees within the organization.

3. 3 Benefits When Businesses Deploy Zero Trust Security

Many business owners ask about ROI (Return on Investment). Here are 3 real values that Zero Trust Security brings:

3 lợi ích khi doanh nghiệp triển khai Bảo mật Zero Trust

a. Minimize Financial Damage

As cited by IBM figures, deploying Zero Trust Security helps reduce remediation costs by nearly 50%. The system prevents Hacker's Lateral Movement, turning a potential attack into a small, isolated incident.

b. Shorten Detection Time from 200 Days to Real-Time

With the old model, businesses took an average of 200 days to realize they were attacked. Conversely, the Zero Trust Security architecture requires Continuous Monitoring, helping detect abnormal behavior immediately.

c. Increase Reputation and Legal Compliance

Applying Zero Trust Security helps businesses easily meet Decree 13/2023/ND-CP on personal data protection, enhancing the Trustworthiness index in the eyes of customers and international partners.

4. 5 "Self-Defense" Steps Following Zero Trust Standards Businesses Can Do Immediately

It is not necessary to invest billions from the start; SME businesses can begin the Zero Trust Security journey with the following 5 self-implementation steps to reinforce the system:

5 Steps to "Self-Defense" According to Zero Trust Security Standards

Step 1: Activate Multi-Factor Authentication (MFA) on All Fronts

This is the simplest but most effective step, preventing 99.9% of account takeover attacks.

• Action: Mandate employees to enable MFA (authentication via Phone App/SMS) for company Email, Cloud accounts, VPN, and management software.

Step 2: Device Inventory and Identification

You cannot protect what you don't know you have.

• Action: List all devices (Laptop, Mobile, Server) allowed to access the company network. Deny access to strange devices or those not complying with security policies.

Step 3: Apply the Principle of Least Privilege

Most successful privilege escalation attacks are due to employees having too many unnecessary permissions.

• Action: Review permissions. Marketing staff do not need computer Admin rights; Sales staff do not need access to Accounting data. Only grant "just enough" rights to work.

Step 4: Basic Network Segmentation

Prevent hackers from jumping from one machine to another.

• Action: Separate Wifi for Guests and the internal network. If possible, separate the network for important departments (Accounting/HR) from the general network.

Step 5: Continuously Update Software Patches

Old software vulnerabilities are a favorite gateway for Hackers.

• Action: Enable Auto-update mode for Windows/MacOS operating systems and office applications.

Note from experts: The 5 steps above are the basic security foundation. However, to achieve comprehensive Zero Trust Security standards (capable of real-time monitoring and automated response), businesses need a specialized monitoring infrastructure (SOC), which is often very expensive to build on their own.

The figure of $92 billion by 2030 is a clear signal showing Zero Trust Security is an inevitable trend of the future. However, the benefit of reducing financial risk by 50% is the urgent reason for businesses to act today.

Don't wait until data is encrypted to start looking for solutions. Let Zero Trust Security become a solid foundation for your business development.
