When organizations strengthen their security posture, three terms come up frequently: EDR, SIEM, and SOAR. All three contribute to threat detection and incident response, so they may appear similar. In practice, however, each observes a different scope and serves a different role.

In simple terms, EDR looks deeply into endpoints such as PCs and servers, SIEM brings security data from across the organization together for analysis, and SOAR connects and automates repetitive response procedures after a threat is detected.

MonitorDog integrates these three operating approaches within screen security. It detects security issues at the endpoint and takes immediate action, centrally manages events from multiple users and devices through a dashboard, and classifies suspicious activity or triggers responses such as screen locking according to administrator-defined scenarios.

In a manufacturing R&D organization, a technology leak rarely stays inside the security team. It can affect a new product launch schedule, expose cost structure, damage supplier relationships, and weaken patent strategy. Design drawings, circuit diagrams, BOMs, test photos, process conditions, and mold data may look like separate documents. Together, they become something closer to a map for recreating a product.

That map does not leak only as a file. Someone may never copy a CAD file, yet still photograph a PLM screen with a smartphone. The same applies to test results on lab equipment, a parts list in a supplier portal, or a large screen in a design review room. The fact that data has not left a file repository does not mean the information has stayed safe.

Security incidents do not always begin with an external attacker breaking through a firewall. A departing employee viewing customer records, a contractor account logging in at an unusual time, or an authorized user photographing a sensitive screen with a smartphone can all become very real threats.

This is where UEBA (User and Entity Behavior Analytics) often comes into the conversation. In simple terms, UEBA is about moving beyond the question, "Does this user have permission?" and also asking, "Is this behavior different from what is normal?"

"Zero Trust" has become one of the most common terms in cybersecurity. But in real-world conversations, it is still often understood too narrowly as "removing VPNs" or "authenticating users multiple times."

Zero Trust is not a single technology. It is an operating principle: do not trust any user, device, or location by default. When you follow that principle all the way through, you inevitably arrive at one fundamental question: when an authorized user has a sensitive screen open, can we really trust what is happening in front of that screen?

Verizon's annual Data Breach Investigations Report (DBIR) is based on real breach data, which is why it tends to surface uncomfortable numbers. The 2026 edition is no exception. Attackers are moving faster, entry points are becoming more practical, and attacks against people are shifting into the work channels employees already trust.

Security investigations usually begin with logs. Teams reconstruct what happened by checking who downloaded which files, where data was sent, and which processes were executed. Incidents involving someone photographing a monitor with a smartphone start differently. In many cases, the logs you would expect to review simply do not exist.

A significant share of enterprise security budgets goes toward DLP solutions. Yet organizations with DLP in place still experience data breaches. This article breaks down what traditional DLP solutions actually cover, why AI-powered screen security takes a fundamentally different approach, and how the two can work together.

Many organizations recognize the need for screen security but struggle to know where to start. A 50-person startup and a 5,000-person enterprise cannot follow the same deployment playbook. The right approach depends on organizational size, industry, and risk profile.

In October 2025, police raided LG Display's factory in Paju, Gyeonggi Province. What investigators found on a suspect's phone told the whole story: hundreds of photographs of internal process specifications and engineering designs, taken with a personal smartphone. The company's DLP solution had not triggered a single alert.

As remote work becomes the norm, the spaces beyond the security team's control have expanded dramatically. An employee's home, a coffee shop, a coworking space — none of these offer the same physical security as an office. And right in the middle of these spaces, a monitor displaying company secrets stays on.

What if someone is quietly filming an employee's monitor with a smartphone while they are working hard? Firewalls and encryption are powerless against this threat. This is Visual Hacking.

A call center agent pulls up a customer's account number, national ID, and loan history — all on screen — while taking an inbound call. A smartphone sits on the desk beside the monitor. At that moment, no DLP alert fires. Call centers and financial institutions handle the most concentrated volumes of customer personal data, yet they often carry the most structurally vulnerable screen security posture.
