Comprehensive Protection from IT Specialist: everything you need to know about SSL/TLS inspection and alternative solutions from Zscaler

Майстер-клас: секрети випікання найсмачніших млинців!

10.02.2025

Transmitting sensitive data over the Internet has become a routine practice for many modern companies. In 2024, 94% of web pages use HTTPS, and, this seems to ensure secure data exchange at first glance. That exactly the same green padlock next to the address looks familiar and secure. However, it also creates the perfect environment for threats concealment.
The point is that modern hackers are effectively hiding their attacks behind encryption, and companies often remain unaware that their traffic has already been compromised.
According to a Zscaler research, the number of encrypted threats have risen by 87% over the past year, proving that traditional security methods are no longer effective.The solution to this issue is here. IT Specialist has accepted this challenge. 
Our experts implement SSL/TLS inspection, thus enabling a thorough analysis of encrypted traffic and the identification of potential threats before they infiltrate the corporate network.
This approach enables organizations to control data transmission, prevent information leaks, and ensure regulatory compliance. For more details on how SSL/TLS inspection works and alternatives available, please explore our article below. Why is SSL inspection important?So, it's clear: the information transmitted through the Internet and protected via the HTTPS protocol can no longer be considered fully secure. Hackers have adjusted to the new realities and now use encryption to conceal their attacks.
SSL/TLS inspection enables scanning the encrypted data. This process follows an "intermediary" principle:
1. Incoming traffic is temporarily decrypted.2. The system inspects it for threats3. If the data is safe, it is re-encrypted and transmitted further.
This approach detects attacks before they cause harm. For example, if a hacker attempts to send malicious code within an HTTPS connection, SSL inspection will "intercept" and block it.
The other significant feature is sensitive data leaks prevention. . Some employees may accidentally or even deliberately transfer corporate data outside the organization. SSL inspection detects and logs such incidents, blocking unauthorized data transfers.
Despite the implementation issues, SSL inspection is an important security protocol. It enables companies to monitor their traffic and minimize cyber threats.

SSL/TLS Implementation challenges challenges of implementing SSL/TLS inspection

Implementing SSL/TLS inspection appears to be the perfect solution to fight hidden cyber threats, why don’t all companies adopt it immediately?The answer lies in the complexity of its implementation. The process is resource-intensive, requires technical expertise, and must comply with legal regulations.
High load on IT infrastructure
Traffic decrypting is extremely resource-intensive. SSL inspection involves working with all company traffic, significantly increasing server load and potentially can slow down the corporate network performance.To understand the scale of the problem, just look at large companies that handle millions of requests per day. Under these circumstances, server performance can drop by 30-50% if the infrastructure is not optimized.The only solution could be a large-scale hardware upgrade, but this requires significant financial investments.
Legal restrictions and confidentiality issues
Different countries impose strict regulations on user traffic analysis, particularly in sectors involving personal and financial data processing. For example, the HIPAA law in the U.S., protects medical information, while in Europe, the GDPR regulates personal data processing. These regulations require companies to ensure user privacy and restrict the ability to inspect user data without a valid reason. As a result, many organizations are forced to use e SSL inspection only for specific types of traffic, thus reducing the effectiveness of the solution and leaving some potential threats undetected.
Hackers bypassing SSL inspection
It’s important to understand that guaranteeing complete protection through SSL inspection is unattainable. Malicious actors are constantly developing new ways to bypass traffic control. Some of the most common methods include:
● Using old versions of SSL/TLS that don’t support modern inspection mechanisms.● Encrypting traffic headers to hide data destinations.● Using DNS-over-HTTPS (DoH) technology, which makes monitoring server requests impossible.
In such cases, attacks can be undetected for a period of time. . That’s why it is important to stay updated on the latest bypass methods and implement solutions that can detect even the most cleverly disguised attacks.
Configuration and maintenance complexity
SSL inspection is not just about installing software that acts like an antivirus. It’s a long process that requires proper configuration, regular certificate updates, and continuous monitoring for new threats.

Browser isolation in the cloud - an alternative to inspection

So, the modern Internet is not only about endless opportunities, but also countless risks. However, a new technology - Cloud Browser Isolation - enables full user protection without relying on traditional threat scanning methods. 
Currently, there are two approaches to security: built-in scanning and isolation. Let's take a closer look at them:
● Threat inspection and blocking - in this case, every data packet is analyzed. If potentially dangerous content is detected, the system blocks it. This method works effectively, but it depends on databases of known threats: if hackers find a new vulnerability that is not yet in the database, the system might miss the cyberattack.● Cloud Browser Isolation - the key feature of this approach is that the user does not interact directly with the website code. The entire page is opened in a remote browser, and the user receives only a visual display. Thanks to this, viruses and other threats cannot reach the device. 
Analysts predict Cloud Browser Isolation may be the new standard for cybersecurity. This technology enables separating the user from the web content, making it absolutely safe to browse. That is how it works:
● the user opens a website, but it does not load directly, instead it opens on the cloud server; ● the entire site code remains on the cloud - only the graphical visualization of the page is sent to the device; ● any virus or malicious code cannot penetrate the system because it is simply not transferred to the user's computer. 
This penetration model completely eliminates the risk of infecting the device. The other advantages include no impact on employee productivity and full control without the need to decrypt traffic. 
The banking sector, large enterprises, and government institutions are gradually starting to implement this method as the main traffic protection line for websites.

Zscaler's Cloud Browser Isolation Solution 

One of the leading players in the cybersecurity field, Zscaler, offers an innovative solution - Zscaler Cloud Browser Isolation. This technology allows organizations to protect their networks and endpoints by completely separating users from dangerous content.
The core idea is that all website content is processed on Zscaler's remote servers, and users only receive a rendered image of the page. Thus, even if a website contains malicious code, it remains isolated and cannot “infect” a device or corporate network.
Here is a step by step breakdown of how it works:
1. User request: when an employee opens a web page, it is not loaded on their device, but in an isolated environment on Zscaler servers.
2. Content processing: all active elements of the website, including scripts and media files, are executed in a virtual browser.
3. Transmission of a “clean” image: the user receives only a secure display of the page, not the actual code.
Thus, even if the website contains a zero-day vulnerability, exploit, or malicious JavaScript, it stays blocked in the cloud environment and will not cause any harm. 
Here how it works :

One of the key advantages of browser isolation is its ability to restrict file transfers, preventing unauthorized downloads and data leaks. Corporate security policies can block or limit file transfers directly through the browser, ensuring tighter control over sensitive information. 
Another critical security layer is clipboard management. Which prevents users from copying and pasting t] sensitive data from an isolated session.
Printing restrictions further reduce the risk of unauthorized data distribution, while read-only access ensures users can view content without interacting in ways that could compromise security.
Isolation also safeguards v against threats that may come through the site's traffic, allowing secure viewing of Office and PDF files within a fully contained environment. Even if a document harbors malware, it remains isolated, unable to spread. To enhance security, users can only download sanitized PDF versions with all active elements removed.
By integrating browser isolation with Content Disarm and Reconstruction (CDR) technologies, the third level of protection can be achieved by transferring files through secure separate channels, thus ensuring malware cannot infiltrate the corporate network - even if a user unknowingly opens a malicious file. .
Automatic sandboxing further reinforces security by analyzing files independently of the main infrastructure.
