What is Robotic Process Automation (RPA)?

Robotic process automation (RPA) uses software bots to handle repetitive tasks that would normally require human interaction with computer systems.

Unlike traditional automation that works through APIs and backend integration, RPA bots operate at the user interface level—they literally click buttons, type in fields, and navigate screens just like a person would. This makes RPA uniquely valuable for automating workflows across systems that weren't designed to talk to each other.

The technology combines rules-based programming with machine learning, letting bots handle surprisingly complex processes. An RPA bot might log into multiple systems, extract data from emails and documents, update records in different databases, generate reports, and route approvals—all without human intervention. Because these bots interact through existing interfaces rather than requiring backend access or API development, organizations can automate legacy systems and third-party software that would otherwise resist integration.

From a security standpoint, RPA introduces both opportunities and risks. Bots need privileged credentials to do their work, making credential management critical. They also create new attack surfaces and can potentially be manipulated to perform unauthorized actions. As RPA adoption accelerates, securing these automated workflows has become a distinct challenge requiring specialized controls and monitoring.

RPA emerged in the early 2000s as companies sought ways to automate business processes without the complexity and cost of traditional enterprise integration. The concept built on earlier screen-scraping and macro technologies but added intelligence and flexibility through advances in computer vision and machine learning. Early implementations focused on simple, repetitive tasks in finance and customer service—things like data entry, invoice processing, and report generation.

The technology gained serious traction around 2012-2015 when vendors began offering more sophisticated platforms that could handle complex workflows and exception handling. What made RPA different from previous automation attempts was its ability to work with any application that has a user interface, without requiring changes to underlying systems. This "non-invasive" approach meant organizations could deploy automation in weeks rather than months, often with minimal IT involvement.

The cybersecurity implications became apparent as deployments scaled. Bots running 24/7 with elevated privileges presented new risks around credential theft, unauthorized access, and potential manipulation by attackers who compromised bot accounts. This drove the development of specialized security controls for RPA environments.

RPA has become ubiquitous in modern enterprises, with bots handling everything from onboarding workflows to compliance reporting. That prevalence makes RPA security critical. A compromised bot account isn't just one person's access—it's often a highly privileged account with access to multiple systems, running continuously without the natural breaks human users take. Attackers increasingly target RPA infrastructure specifically because successful compromise delivers persistent, automated access to valuable data and systems.

The security challenge extends beyond credentials. RPA bots follow programmed logic, which means they'll happily execute malicious instructions if those instructions reach them through compromised workflows or manipulated inputs. Unlike humans, bots don't notice when something seems suspicious. This makes controls like input validation, activity monitoring, and segregation of duties essential rather than optional.

Organizations also face audit and compliance questions around RPA. Who's responsible when a bot makes a mistake or performs unauthorized actions? How do you demonstrate proper controls over automated processes? These governance challenges intersect with technical security concerns, requiring a comprehensive approach to RPA security that addresses technology, policy, and oversight.

Plurilock's identity and access management services address the core security challenges RPA creates. We implement proper credential management, segregate bot accounts from human access, and establish monitoring that detects unusual bot behavior without generating false alarms.

Our work with government and enterprise clients means we understand both the security requirements and the operational realities of RPA deployments. We help you secure your automation without losing the efficiency gains that made RPA valuable in the first place.
