TalForsher
I focus on application security, exposed data, and AI vendor risk — connecting what an application shows with what it actually exposes.
& APIs
Intelligence
Beyond the Interface. Into the Risk.
I’m Tal Forsher, a cyber security specialist with a software engineering background. My work connects application security, data exposure, and AI vendor risk through security-focused products and hands-on investigation.
Exposure Discovery
Investigating the gap between what a public interface displays and what its underlying APIs reveal.
Application Security
Focusing on access boundaries, data protection, and the difference between public and authenticated access.
AI Vendor Risk
Making third-party AI risk easier to understand through the vendor intelligence work behind Forshrr.
An Engineer’s Perspective
Drawing on production software experience to connect security findings with practical changes to applications.

The Problem
Component re-rendering too frequently, causing UI lag with large datasets
// Before: Unnecessary re-renders
function DataTable({ data }) {
const [filter, setFilter] = useState('');
const filteredData = data.filter(item =>
item.name.includes(filter)
);
return (
<div>
<input onChange={e => setFilter(e.target.value)} />
{filteredData.map(item => (
<Row key={item.id} data={item} />
))}
</div>
);
}// After: Optimized with memoization
function DataTable({ data }) {
const [filter, setFilter] = useState('');
const filteredData = useMemo(() =>
data.filter(item =>
item.name.toLowerCase().includes(filter.toLowerCase())
), [data, filter]
);
const debouncedFilter = useDeferredValue(filter);
return (
<div>
<input
onChange={e => setFilter(e.target.value)}
value={filter}
/>
<VirtualList items={filteredData} />
</div>
);
